I have several suggestions on this tool :
1 - warp tool and bloat tool should have the same sensitivity. Now, with the same intensity they react extremly differently. I often have to open the dialog box, which is laborious so :
2 - Find a way to adjust the tool without opening the dialog box,
ALt + click = change the size
Alt + Shift + click = change the size proportionaly
Alt + Ctrl + click = change the intensity and voilà!
3 - Is there a way to keep my tool setting, because it is very laborious to change it at each startup.
