iPad display with Painter 2019


Are there any general tips for enlarging the overall display of the Painter interface on an iPad Pro 12"?
The tool bars are so small that eye strain becomes a problem, I know that I have the zoom options but that enlarges the canvas and the tools disappear meaning I have to use the mouse to select options - not the largest problem in the world but it does interrupt the work flow a bit.

I use an iMac 27" running Mojave and a 12" iPad Pro - the Painter version is 2019
