First of all, thanks again for sharing your work and for constant updates!
I just installed last patch ("Modify Collection Count Behaviour") and I'm experiencing a problem...
When this patch is enabled, the GUI launcher seems to be slower.
This means it takes longer to refresh the screen when tapping on launcher and also when tapping on a item with a submenu in the launcher.
I can see the home screen in the time the launcher opens a submenu.
With that patch disabled, everything is a bit faster.
I tried uninstalling JBPatch and installing it again, then I tried enabling and disabling the patch and this happens only when the patch is enabled.
Here are more info:
