Add an option to bring back the old resources tab

[Iguas]

The new system is about the same as the old one except it's now in a separate window that we need to open and close every time we want to check resources (all the time).

I understand that having littles icons is a good idea, search feature too, and choosing what to show/hide is geat.

BUT, alphabetical order is just not working, if you want to monitor a lot of resources, you just end up getting lost.

Adding a way to sort resources by category, just like old times, or like the window works now would be a lot easier.
