this is one of the most important tools on photoshop, WHY is it not on photoshop mobile??? it seems like a terrible mistake. Photoshop mobile is a very watered down version of Photoshop version. As for now, i find it pretty useless.
Everybody thinks that the tool he/she's using most must be the tool that everybody is using most. In reality that is hardly ever true. I never use the slice tool, for example. Adobe knows what tools people use often and what hardly anybody uses (because of the anonymous feedback that Photoshop sends back). They do take that into account, because that is exactly why they get that kind of feedback.
