UI changes in xfce4-settings-editor?

[Jérôme Guelfucci]

Hello,

I'm working on adding two missing features to xfce4-settings-editor: 
adding channels and removing/resettings channels. Obviously this 
requires some changes in the UI.

I see two options. First only have one add button and one remove/revert 
button and make it act on the selected treeview (if the property 
treeview is focused, it creates a new property, if the channel trreview 
is selected it creates a new channel). The buttons would then be 
displayed as a toolbar on top of the two treeviews. However, having the 
same button for two different actions might be a bit weird and not easy 
to understand.

This leads two the second option, adding two other buttons. But where 
would we add them? Moreover, it would be bad if they looked exactly like 
the buttons for the property stuff, so we need to find some way to make 
them different but still understandable.

I'm open to all suggestions, I'm not sure I was really clear so don't 
hesitate if you have questions. My branch for xfce4-settings-editor is 
available on git and is called jeromeg/xfce4-settings-editor, feedback 
is welcome.

Cheers,

Jérôme
