We briefly had time to play with AstroPad Studio before our trial ended, but thought enough of it to purchase for the one-year subscription. Now that we are starting to use it for real work on a daily basis some issues are rearing their heads and we're not entirely sure how to proceed.
For right now, let's just discuss Photoshop CC (2017) and know that all functions are flawless on the Macbook Pro or Mac Pro that we are using. This is entirely related to AstroPad Studio.
Undo/Redo work perfectly and without delay, however pinching to zoom and rotating the canvas does not. We can do the gesture again and again and at some point it may get us to where we needed to be but not without quite a bit of effort (i.e. much faster to do this on the Mac instead, which defeats the entire purpose of using a "tablet").
Changing Brush Sizes
Having to hold down Cntrl+Alt and drag left/right is fairly cumbersome using AstroPad Studio and while I understand that you have built in the buttons to repeatedly tap to change the brush size up/down, we need to be able to drag left/right and move faster. The more tapping and slower the change, the more you lose the creative side and start thinking in the technical/computer world.
Are there ways to create Macros of some sort where we could have a single button that would press both Cntrl and Alt and allow us to drag left/right to change the brush size?
The Eraser Shortcut
It seems that using the Magic Gesture to enable the eraser tool only works if you have the brush tool active. However, if I have the move tool active and try to press one finger and use the Pencil all it does is move the canvas. It would be great to be able to use the eraser from wherever you are in the application, not just if you are already on the brush tool.
