This is a fork and further development of Research Tree (Continued), maintained by Mlie:
https://steamcommunity.com/sharedfiles/filedetails/?id=3030499331
This version is focused on large mod lists. It reworks research tree generation, layout, rendering, navigation, filtering, profiles, and queue planning so the tree stays faster, cleaner, and more usable with hundreds of mods and complex Research Tab setups.
Main features:
- Much faster research tree generation in heavily modded saves.
- Cleaner and more compact layout with reduced visual clutter.
- Smoother dragging, WASD movement, scrolling, and zooming on large trees.
- Research Tab filtering and multiple Research Tab profiles.
- Optional hiding of completed projects.
- Improved compatibility with Organized Research Tab, Semi Random Research, Anomaly research, and Vanilla Gravship Expanded Gravtech.
- Separate system views for Anomaly and Gravtech research, using their original research flows.
- Improved research queue with drag reordering, one-click clear, dependency-safe ordering, and dependency-path planning.
Known issue:
- The first time the research tree is opened after loading a save, the game may briefly stop responding while the tree and caches are generated. Later openings are usually much faster.
Changelog:
2026.05.13
- Improved support for huge modded research trees, with smarter route highlighting, less visual noise, and better handling of dense dependency graphs.
- Research queue planning is more reliable across filtered tabs and profiles, including hidden prerequisites and queued projects outside the current view.
- Anomaly research now refreshes only when vanilla reports a newly discovered anomaly that actually changes research visibility; repeated fleshbeast spawns no longer rebuild the Anomaly tree.
2026.05.12
- Added the Research Planning Bar. Hover a project to preview its dependency path, press Space to pin it, then append, insert, or replace the queue.
- Improved queue editing with drag reordering, clear queue, insertion markers, remove buttons, cascade removal confirmation, and dependency-safe ordering.
- Improved dense-tree readability with route highlighting, unrelated-node dimming, cleaner info cards, and reduced dependency-line clutter.
- Optimized planning path calculation for large trees.
2026.05.11
- Added dedicated system tabs for Anomaly research and Vanilla Gravship Expanded Gravtech.
- Improved special research display, switching, undiscovered Anomaly states, active research highlighting, profile zoom handling, and queue preservation.
- Improved research profile UI and related localization.
- Fixed stability issues around special research trees, cyclic dependencies, unusual layouts, and cached profile switching.
- Fixed the mod name and PackageId typo: ResearchTree / eheieh.researchtree.
Older changes:
- Added Research Tab profiles, profile management, profile reordering, and top-bar profile switching.
- Added Research Tab selection/filtering and saved filter state.
- Added completed-project hiding, connection-line toggle, and Shift-click queue replacement option.
- Improved Semi Random Research compatibility and research entry button behavior.
- Improved node availability detection, dependency detection, path detection, compact spacing, dragging smoothness, and scrollbar behavior.
- Fixed crashes and edge cases involving empty Research Tabs, no selected tabs, invalid saved tabs after mod removal, closing the tree tab, and large research progress values.
