Hey everyone,
We've just released an update to the develop preview with the following changes:
General
- The Disable and Remove Bands buttons now have new icons
- Added an option to allow GUI scripts to run while minimized in windows
- Hovering over the undo graph will now show the score
So you can see the new icons without needing to download and install devprev:

As far as I can see the update to enable GUI scripts to run when the client is minimised is not working. There seems to be little if any progress when minimised.
You will have to add a line to your options file in order to turn this on:
"update_while_minimized" : "1"
