I could use a pop-up filebrowser that expands with each subfolder like the file-browser-applet for gnome 2.x I coach high school debaters and they need to be able to access and easily sort through hundreds of different files organized in various folder structures very quickly and efficiently.
I'm a pretty new user to linux, my conversion is mostly an economic decision for supplying poor kids with cheap/donated used laptops, and not having to deal with a giant book of education software licenses.
This is what we are currently using and it's pretty fantastic for what we need it to do. At the moment, it seems that all the primary desktop environments have forgotten about shortcut access to large file tree structures, or I'm just not finding the ones that are out there and still work/are supported.
