dragmapr 0.2.0

• drag_map_prototype() gains an optional transition argument: the browser helper runs one client-side leaf-flip branch animation for parent-to-child bloom and child-to-parent unbloom, and draws a dotted group-drag boundary per expanded group. Clicking a boundary posts a dragmapr-collapse-branch message to the embedding page, or resets the branch when the helper runs standalone; a plain click on a region posts dragmapr-region-click.
• New inst/examples/branch-bloom-tester.R Shiny example isolates the branch-bloom helper so clean bloom and leaf-flip behavior can be tested without the full Spatial Studio shell.
• New packaged cheatsheet in inst/cheatsheets/ covers the core workflow, labels, static rendering, Spatial Studio, hierarchy/bloom helpers, CRS diagnostics, layout snapshots, and transition utilities.
• New upload intelligence helpers: detect_hierarchy_columns(), recommend_dragmapr_hierarchy(), validate_bloom_hierarchy(), build_branch_transition_data(), make_branch_bloom_labels(), summarise_spatial_crs(), and profile_spatial_upload() move parent/child detection, CRS meaning, branch-bloom data prep, and safe parent-first label setup into reusable package functions.
• Spatial Studio: new Bloom sidebar section. Pick a child column (“bloom into”), then click a parent region on the map (or choose parents in the panel) to expand just that parent into its children with a leaf flip - the rest of the map keeps the parent grouping. At most two parents can be expanded at a time (expanding another replaces the oldest), the dotted reset boundary can be toggled off, and clicking the boundary or the children compresses the branch and restores the parent’s saved position. The bloom target must genuinely nest inside the current grouping (data-driven check with a clear error otherwise). Arming bloom embeds both parent and child keys in the helper once; expanding and collapsing then run fully client-side over postMessage, so there is no iframe rebuild, no loading overlay, and the animation always plays. The dotted frame is also the group’s drag handle: dragging it moves the whole expanded branch (children, labels, and frame together), and collapsing places the parent at the mean of its children’s positions. With “Dissolve to parent shells when collapsed” (on by default), child-level uploads display as clean dissolved parent outlines until a parent blooms, which both sharpens the reveal and reduces the number of drawn shapes.
• Spatial Studio: the Bloom panel now includes an animation selector so users can switch between the leaf-flip proxy animation and the clean branch-bloom animation. The selected mode is sent to the live helper without rebuilding the iframe.
• Spatial Studio: one unified full-app busy veil replaces the previous mix of map overlay, sidebar freeze, and full veil. Two modes share the same blocker - “Loading spatial data” (uploads, project opens) and “Processing changes” (helper rebuilds) - with lock counting so overlapping tasks never hide the veil early, a short show delay so fast rebuilds don’t flash, and safety timers so a missed release can never freeze the app. The Shiny busy state only drives the slim top progress bar; client-side bloom interactions never show a veil.
• Spatial Studio fixes for files with arbitrary column names: hierarchy detection on column switches is data-driven (the child column must actually nest inside the parent grouping), and the default group/region column detection no longer assumes specific column names or excludes one-row-per-region files (e.g. COUNTY_NAM instead of COUNTY).

dragmapr 0.1.0

Initial CRAN release.

• drag_map_prototype() writes a self-contained D3 browser helper where grouped sf regions, labels, and annotation boxes can be dragged freely. It exports region and label offset CSVs.
• render_dragged_map() reconstructs the dragged layout as a ggplot2 image from the source geometry plus offset tables.
• render_dragmapr_project() renders a complete Spatial Studio project bundle (ZIP) in one call.
• make_region_labels(), as_drag_labels(), and as_drag_annotations() build label tables; read_label_state() and apply_label_state() restore saved label positions.
• read_offsets() and apply_offsets() handle region offset I/O.
• read_dragmapr_sf_upload(), read_dragmapr_sf_url(), and prepare_dragmapr_sf() read and normalise spatial files for Shiny workflows.
• dragmapr_iframe_bridge() provides the JavaScript bridge for relaying drag state from the helper iframe back to Shiny inputs.
• dragmapr_addin() registers an RStudio gadget under Addins > Launch dragmapr that embeds the prototype in the viewer pane and assigns region_offsets and label_offsets to the target environment on completion (.GlobalEnv when launched from the RStudio Addins menu).
• Interactive and static outputs support selective legend and label rendering with legend_values and label_values, preserving stored offsets for hidden labels.
• Label connector lines can be styled by color, width, line pattern, and arrow endpoint in both the browser helper and static exports.
• Movement context controls can show origin outlines, movement connector lines, and browser-only drag preview trails. Movement connectors support configurable color, opacity, width, line pattern, and open/closed endpoints.
• Spatial Studio demonstrates legend and label multiselect filters, connector styling, movement context controls, project persistence, and static bundle export.
• Release hardening: package-internal %||% is defined for the RStudio addin, prototype output defaults to a temporary HTML file unless file is supplied, connector linetypes are validated in static exports, the Shiny iframe bridge stops polling on disconnect/unload, CRS-less inputs warn before assuming the target CRS, legacy label helper aliases emit deprecation warnings, and the bundled D3 license is included under inst/prototype/.
