Hello!! I've been using krita for about a year and a half now and I've always been eager to see what the new updates bring, but the latest update -4.1- has been a bit...disappointing(?) for me personally. It's not for the content that was updated, of course - I'm happy to see the reference window back and better than ever!

The problem is rather that in previous versions of Krita, I enjoyed being able to use the buttons on the side of my tablet pen to navigate the canvas. One allowed me to move the canvas around, much like the Pan tool but easier and faster, while the other let me to zoom in and out, as well as rotate the canvas. In 4.1 this doesn't seem to happen anymore? I'm not entirely sure if this is an issue with my tablet driver or if this is something that can be changed in the settings somewhere? Or if it's just been removed entirely?

It's a bit disappointing to me since these pen interactions were one of the main reasons I enjoyed Krita so much, and also the main reason I personally couldn't find it in myself to switch to other programs like ClipStudio or Photoshop. I'd be heartbroken if they're gone for good - does anyone maybe know if there's something i'm missing in my settings since the update? Or if my tablet driver might be responsible?

In Krita there are settings for shortcuts and for canvas input, this last place is where you set how the pan, rotate and zoom gets invoked, here you can set a combination of a pen button, pen stroke, pen hover, pen click plus a key (or any set of them). The defaults are very "ergonomic" already, like Shift+stroke = brush size (my favorite).

I didn't understand though if when you said that previously only pressing one button on your tablet would pan/rotate, etc. or if it was the combination of a tablet button plus a pen hover/stroke.
In either case, you can try to set in the shortcuts or canvas input settings a key shortcut for those actions (note: the shortcuts act in increments like zoom specific percentage every time the key gets pressed, etc. unlike the smooth behavior of the canvas input settings).

Depending on your system and tablet driver/software, the tablet and pen buttons get a specific "map" of the keys they represent, thus for example the usual two buttons on the pen represent the middle/right click of a mouse while the point represents the left click of it. In many tablets this can be changed to the users liking. Same goes for the tablet buttons. Thus if you want to rotate for example only using a tablet (without the keyboard) the usual way is to set one of the buttons to "Shift", like this pressing on it while hovering the pen sideways will rotate the canvas accordingly, and so on.

Thus if it was working and isn't any more, I would recommend to check both, first the buttons assigned to your tablet (through its driver/software) and once you know what keys they represent, then make sure Krita is using them in the Canvas Input Settings.

Although I'm not 100% sure, I don't think there was any change to this functions of Krita in the new version.
