Compatibility of Maingraph for MC

Known compatibility with the following mods:

  1. IMBlocker: Since v0.2.2, the Blueprint Editor uses Minecraft’s native EditBox, making it compatible with IMBlocker.
  2. Just Enough Characters: Starting from v0.2.3, the Blueprint Editor fully supports JECh via reflection.

    • Current Status: When JECh is detected, the search feature automatically enables Pinyin initial matching (including node names, categories, port names, etc.).
  3. Physics Mod: In F6 physics UI mode, the Blueprint Editor does not participate in physics simulation.

    • Planned Fix: No fix planned.
    • "Does anyone actually edit with this thing on...?"
  4. ImmediatelyFast: Testing shows no noticeable FPS improvement in the Blueprint Editor after installing ImmediatelyFast.
