Tilt in name means brush stroke changes when you tilt the Pencil.
In Sharp Pencil - it simulates tilting real pencil, and painted dots are scattered.

You have to show Rulers first - tap View->Show Rulers.
Then active Move tool. And drag guideline outside the canvas.

I havent change dodge/burn for few months. Maybe you are using different brush. Default brush for dodging/burning is Soft brush from Basic group

Indeed you can use use layer blending with Paint tool instrad of Dodge/Burn tools.
But dodge/burn tool has 2 advantages:
1. You can limit effect to shadow/midtonrs/highlights
2. You can draw few strokes over the same area to “build up” dodge burn effect

There few methods that are working for sure:
- use airdrop to send them from computer to iPad
- upload them to iClod drive on computer, then open them using Files app, or tap in artstudio Import ABR/TPL
- send by email
- use “Open In” button in Safari
- use Readdle Documents app

My fav method is Airdrop or iCloud Drive
Im not sure about Google Drive, it should work. I will check it after Christmas.

File sharing/User Rrsources doens not work, because brushes stored there must use artstudio format

Ok, we will fix it
