Inspectors and windows
Custom inspectors, property drawers, and editor windows. Menu items go under menus people already use.
Runekit
Editor tools for 3D and game software.
I write tools that run inside the host application. They are small, dependency-free, and specific. Custom windows, inspectors, and menu items that have to stay honest through undo, reload, and someone else's project layout.
What I build
Project data
Settings that survive a reimport and do not depend on hidden objects in a scene.
Fit
Code lives in my own namespaces. It does not belong in the host's, and it does not belong in yours.
Tools
Blender
Casegen. Parametric project box: inner cavity, wall, lid lip, screw bosses and vent slots in millimetres. $60
Unity
Localization Preflight. Editor-only checks for Unity Localization and TMP. It tells you before you build. $35
