We like the drag and drop for splitting items but want to be able to split checks 2,3 or 4 ways without having to move a bunch of items. That was a great feature overlooked on thrive, many people just want to split big orders down the middle.
This feature has been completed and is available in the 8.0 version of Thrive.
I think we used to have an option in Thrive to click on the splitter icon (looked like a fork) and the keypad would come up asking how many ways to split. Now we no longer have it and I miss it!
