Hi Somerset 
The Stencils panel can be Docked or Floated as desired.
At the top of the Stencils panel is the ‘Active’ tab which will show you all the stencils currently being used and their Visible states.
Hovering over a stencil's thumbnail will bring up a Menu icon for further action for that stencil.
The Toolbox question is an interesting one? And I too think it might be a bug.
Add a stencil to a toolbox and then save that toolbox to disk.
Then remove said stencil from the painting and it disappears from the toolbox. OK, not ideal but I can sort of live with that.
But now if you reload the toolbox you just saved containing the stencil, it should be in there again, but it isn’t? That shouldn’t happen, and it doesn’t happen for other brushes etc…
Worth reporting.
As for the text tool, well for me personally, I don’t see Text as an area that AR should overly focus on. For me it’s primary focus should be as a real media paint simulation program.
I tend to use text in AR as temporary filler text, and then use another program if there is a lot of text to do.
But don’t get me wrong, any improvements made to the Text tool would be greatly appreciated!
Giving X, Y, cordinates for stencils?
I like that, could be useful.
