[Goodies-dev] Proposed goodies contribution: Recent Folders v0.1.3

[Serge Stroobandt]

Hello,
Below is a slightly improved version of the proposed goodie plugin.
Recently used folders are now listed in alphabetical order, which works 
much better than chronological order.
I will contact the developers of http://pyxfce.xfce.org to see if I can 
get some assistance with proper plugin integration.

Furthermore, I would really appreciate to receive some feedback from 
this group.
If this contribution would be considered futile by this group, I would 
like to know why
so that I can move on and get it hosted elsewhere (freedesktop.org for 
example). But that would be a real pity.
All I can tell is that this plugin is helping me a lot during my day to 
day real work using the XFCE desktop!

#!/usr/bin/python3
