Optimize photoshop elements for graphics tablet?

Hello, I would like to request some features, I wonder if Adobe team can listen to us?
I was wondering if there will be the  possibility in future to optimize the interface of Adobe Elements also for a graphic tablet (drawing tablets?)  (I mean, no 'wacom', I mean tablets in the sense of , like the samsung tab s7 FE for example. This sort of tablets)
I need to use the brush to painting over an image and I need to pick up every 3 seconds the colors. With the brush I can pick up the color by hold ALT and when I release ALT , it became again a brush. This is very useful when one painting and to do this with a mouse is pretty simple. But when I want to use my drawing tablet to be used, instead of the mouse, I use the pen of the tablet, there's no option in the Adobe Elements to customize the button of the pen, and assign a specific commant/key, like in this case "ALT".
So I have to keeping to move the pen on the eyedropper tool , pick up color, then again and select again with the pen on the brush. Then again select with my pen the eyedropper tool, paint two seconds and again I go to move the pen again  and pick up the brush and this for all the operations I would need to press a specific key, I can't associate a key to the button of the pen , for have for example  key shortcuts associated to the button of the pen of the tablet.
I hope they will add this feature one day?

Also, regarding Photoshop Elements, I noticed (I'm testing the trial version), when I use it on my computer (I use windows 10)   I noticed that sometimes, the software don't respond anymore to the commands, it's like if it 'freeze'. After some seconds (many seconds) suddenly start to make things again, like if I have to drawing and I want to change the size of brush, I click over the 'circle' to move it and change dimension, but it seems like is 'freezed', I mean, don't move at all. After some seconds (many)  it start to move again.
I also noticed other freezing, here and there. Is because it's trial or is normal for who use Windows10 with 4 gb of ram? I also noticed something strange happens, like for example some layers disappears (even if I don't press anything to delete it). Like I do an operation on a layer , (I don't remember what exactly), but I noticed it was something that have nothing to do with cancel or modify a layers, but after that operation, a layer disappear (no the current layer I was doing certain operations, but another different layer). Or something. Of course  I can't still understand exactly what happened, if I will find out some details that can describe better i will tell you. But I see there's 'strange' things that happens, even if is hard to describe or remember in which specific occasion. This happens also to others or it's my windows /features of my pc? ram, etc?

Thanks again for all the helps!
