Menu Bar Select/ Modify / Floating Popout

There may already be something out there on this.

Working in Selection mode and want to make more than 1 change to a selection. I find I am able to only select one item ie "Expand" a follow on dialogue box appears as to how many pixels then disappears.

Be great if the user can change more than one thing here. 

I know the Select and Mask screen allows multiple changes. However, be nice to be able to float the Modify screen out IOT make mutiple changes. ie Expand and Smooth.

PS is an awesome program. Just wanted to see what others think.
