I made the following changes to the Resources category:
Add Aseprite to Game Development Tools, under Graphics Editors. It feels odd not having a pixel art focused program here, aside from the passing mention of using Paint.NET for it.
Add LDtk to Game Development Tools, under Map Editors. LDtk is a very Haxe friendly editor with HaxeFlixel integration, so it makes sense.
Fix the inconsistent headings. Map Editors and Asset Utilities had bigger headings than the other two sections.
Add a section to Using Haxelib about using libraries in your project after you install them.
