I got a myglcd to play with.
eg using ili9341 the read pixel works and you showed it's a 1x1 pixel window so could a row of pixels be read and stored if the window size was changed? could become scrolling or other use.

The methods you have found are used in several programs. They may not be published in the Help.

If you have time to create a few pages of Help based upon https://github.com/Anobium/Great-Cow-BASIC-Help/blob/master/source/box.adoc or some similar Help page then we can add these to the Help on the next release.

Need help to do this stuff.
