Ability to Define Browser Tab Paths

Title may be a little confusing but I'm talking about the tab's on the left with the built in instruments, presets, projects, samples, etc. It'd be nice to be able to put any folder you want there or even just to change the paths of the folders that are there, tried putting shortcuts to my samples in the "my home" folder as a workaround but it didn't work, also tried to find a config file with the paths but didn't have any luck with that either

Start by locating the built-in browser tabs for instruments, presets, projects, and samples, then trace how their folder paths are currently defined. Determine the configuration and UI changes needed to support custom folders or changed paths; done means users can select arbitrary folders and those locations appear in the relevant tabs.
