HELLO! Over the past couple of days I worked on some editor enhancements to the Project and Heirarchy windows. Project Window * Shows file extensions (can be set to only show them when duplicate filenames are present) * Has a pop-up quick preview if you hold the mouse over an item * 'Useful' tooltips are also shown per item Heirarchy Window * Shows icons for each component on the gameobject, which can be disabled/enabled by clicking * Has a pop-up quick preview if you hold the mouse over a gameobject or one of it's components * 'Useful' tooltips are also shown per item and per component Settings There are some settings in Edit / Preferences / Project Window Heirarchy Window - however they're kinda broken at the moment. For example, you can set the Project Window not to show all the extensions, in which case it will only show them if there are two or more files with the same name Installation You can grab a ZIP of the code here: EditorEnhancements.zip - just copy the EditorEnhancements folder into your Assets folder. The bitbucket repository for the code is here. I have tested on Unity 3.5.5, and Unity 4b7. Please tell me how you get on with it, and if you want anything else added Versions 1st Sep - Supports missing scripts better, no longer truncates icons, and toggling components via their icons is now undo-able. 1st Sep B - Quick asset preview if you hover the mouse in the project window. Also strikeout hierarchy items if they're not visible in the scene view due to layer settings. 5th Sep - Now has a quick preview window if you hover over gameobjects or their components in the hierarchy window.
