I wanted to have an faster access to certain assets, so I created this addon which adds any amount of “Resource Browser” panels to the bottom bar.
Each panel has different config. You can add locations to search from via drag and drop, and filter files by extension (eg. mesh, tres) or type (eg. Mesh, Material).
Released it publicly if anyone else thinks it would be usefull. It’s under MIT license.
This might be useful for really big projects, but for me it seems like I might as well use Quick Open with Shift+Alt+O and type the file extension to get a list of all the files with that extension.
