Drag It!

Overall

• First public pre-release: drag & drop for the vanilla resource pack and data pack selection screens.
• Dragging a pack lifts it as a card that follows the cursor; the other packs slide aside and a placeholder marks the exact slot where it will land.
• Drop inside a list to re-order, or into the other list to enable or disable the pack at that exact position.
• Dropping outside both lists, or pressing Esc, glides the pack back and keeps the screen open.
• Dragging near the top or bottom edge of a list scrolls it, faster the closer the cursor is to the edge.
• A plain click behaves exactly like vanilla: the arrows enable, disable, and move packs, and a click selects.
• Multi-selection like in a file manager: Ctrl+click toggles a pack, Shift+click selects a range, Ctrl+Shift+click adds a range, and Ctrl+A selects every movable pack of a list.
• Dragging a selected pack lifts the whole selection as one block and keeps its inner order.
• Enter, Space, or the arrow of any selected pack sends the whole selection to the other list; pressing it again brings the selection back.
• Pinned packs (fixed position) are never lifted and nothing can be dropped across them; the blocked spot is marked in red with a "Fixed position" hint.
• Required packs such as the built-in Default pack can be re-ordered but never disabled.
• Dropping a single incompatible pack into the enabled list shows the same confirmation dialog as vanilla.
• Selection highlights fade in and out instead of switching instantly.
• Animations run on real time, so they look the same at 30 and at 300 FPS.
• English and Russian translations.

Compatibility

• Minecraft 1.21.1 on Fabric (Fabric Loader 0.16.4 or newer) and NeoForge (21.1.259 or newer), Java 21. Client side only.
• Fabric API is not required.

Architecture

• One Stonecutter source tree builds the Fabric and NeoForge targets, with tag-driven publishing to GitHub, Modrinth, and CurseForge, mirroring the Handycam build and release setup.
• Official Mojang mappings on both loaders. The mod id is dragit (NeoForge does not allow hyphens in ids) and the code lives in the dev.vercim.dragit package.
• The build fails if a JAR does not register its Mixin config, misses a mixin class, or contains the other loader's files.
• Added the pixel icon and declared LGPL-3.0 in the mod metadata, matching the bundled license file.

Documentation

• Added README, development and release guide, and version notes.
