It is now possible to import custom resources via the user interface (File > Import custom resources) in addition to the command line tool. Updated the user guide with explanations on how to use this new interface.
Two new options are available for gchlib: -pck and -npck for gchlib list item. This can enumerate all the items that are (pck) or not (npck) in a pack.
Improved:
Improved "Export as PNG" window. If the selected output file already exists, the spritesheet to export will be drawn over the existing image in the preview area.
Improved user guide with explanations on how to properly export RPG Maker MV Face/Damage spritesheets (In section "2.5 - Export character").
Added new frame mapping processes in the RPG Maker MV pack.
Bug fixes:
Fixed a rare case where selecting frames would make GCH stop.
Fixed the issue where changing the layer composition mode made the layer turn black.
Fixed rare issue where the "Edit character's dimensions" window would crash if it was validated with some wrong input.
Fixed RPG Maker VX Ace pack: the frame mapping processes were not properly configured.
Fixed issue where the recoloring option that features HSL sliders in item explorer would not recolor properly.
Fixed the frame mapping processes manager window: some parts of the window were not properly disabled for some settings.
