Hello!
I suggest to improve"SEPARATE" operation in mesh workspace. It will be OK if to add ability to select all faces in "SEPARATE" operation to make all the selected faces separate in PATCH workspace. It's not easy to select one face after another face to separate them all.
Some description under the pics.
Separate operation allows only one face to select if to click separate option first.If push "Ctrl" first i can use this operation to separate some faces. But in Patch workspace it's detecting like one surface.
