Can we have Crossfade curve on screen one touch switching please.

Can we have Crossfade curve on screen one touch switching please.

This feature is so desperately needed now when using Djay with a controller.
It is far too much hassle at present having to navigate through the menus to find ‘Cut’ mode on the crossfader when you want to have a quick scratch.
The software/app needs a button/switch on the main screen so this can be quickly toggled.
Please add this to the next update.
