How about adding functionality to open zipped GP and PTB files? They're pretty big, and it just seems like a nice and easy thing to add.
Also, maybe give the buttons a bit of colour. It looks like they're all greyed out, and it makes it easier to identify buttons with different colours i.e. A green play button, and a red stop button.
Mmmm...
I would personaly need such a plugin.
Maybe to (try to) open the largest file inside a ZIP archive?
And I am thinking... Batch file converter is just finished. That means if ZIP plugin is loaded, it would try to open all the ZIP files inside the folder. But then again, it tries to open everything inside given folder, whatever it is. :)
It is easy to implement, but I'm still not sure if it is a good idea. Julian?
