Hi, I am pleased to report that we have been working through some of the items mentioned here:   - In Photo 1.8.3, the [ and ] keys will step the Pixel Brush in exact, single pixel sizes. - Brush rotation is already available using the left / right arrow keys. - We have added the ability to create brushes from the current selection in Photo 1.9 - which will become available in beta in a few weeks. - Circle selection can be set to "from centre" in Photo 1.9.
