Took you three minutes and fifty seconds to compile and upload, i suppose?
... i like it, but its too easy to loose the cursor? May i ask you to make it a circle, with several options?
Something like, ...
1st, Regular fully visible.
2nd, Maybe the crosshair you get in the empty layers panel that would disappear once you apply paint?

3rd, Just a white pixel that disappears once you apply paint?
4th, Maybe, uhm ... four small dotts that move along each of the canvas edges showing the brush locations cross section, you know?

5th, Fully hidden.
Huh, i am just pooling again, five seem like too many already actually, im sure you find some nice middle ground, or lets wait for some other user's input?
Hmm, since LiveArt's request was for recordings this may would mess it up again, but
i wouldnt mind if [Space] Brushsize would
always show up.
[Shift]+[Ctrl]+[Alt] Canvas rotation also could have its own cursor icon that would alwas show no matter what state youre in.
And, moving the cursor outside the canvas could always show an icon of some kind too, so you see where you exit ... maybe that layers panel crosshair, again. (kinda like that one)
AAAAaaaand, speaking of little features you keep forgetting

, how about that "click,select layer"

...
i often have my color pallet on a different layer and have to reach for the panel to pick without shading.
A 3rd pick "from all layers but without shading" would do it already actually, whatever is easyer
