Architect Icons adds visual cues to the Arrchitect Tab. No more random clicking to find stuff!
If a mod isn't supported, a placeholder icon is used. You can suggest icon support for specific mods. In the future, there might be an API for mod authors to include icons.
FOR GAMERS:
To add your own icon or change an existing one, go to the ArchitectIcons folder where your saves are located [example "C:\Users\Marcin\AppData\LocalLow\Ludeon Studios\RimWorld by Ludeon Studios\ArchitectIcons"]. In there you'll find a text file containing the names of all the tabs you have in your game. The list is created on game launch with ArchitectMods enabled. Just create a 16x16 PNG icon with the filename like one of the tabs, case sensitive, and put it next to the text file. Your icon should be added on game launch.
