K2PostIt (UE5.4 to UE5.6)

This is a fairly small plugin which is intended to look down upon Unreal's very annoying "Comment" node. Don't get me wrong, the "Comment" node is great for wrapping/labelling blocks of blueprint graph, but it's hardly a comment node!

This plugin is currently for the Blueprint Graph only. More graph types may be supported later.

Usage/Features

• Press Alt+C to place a new comment node.
• Markdown-style support (supports basic markdown; advanced markdown capabilities may be added later)
• Realtime rendered markdown preview pane.
• Preset quick-selectable colors, editable in project settings.

Notes/Known Issues

• Currently tested for UE 5.4+ only. It may be easy to make this plugin work on older UE5 versions (the main limit preventing older versions is due to TInstancedStruct usage instead of FInstancedStruct).
• Not all markdown is supported. The preview video above shows currently available formatting.
• The inline code markdown style cannot auto-wrap inside of itself yet; you may occasionally need to split up inline code markdown manually into chunks so SRichTextBlock can wrap it.
