1) Ah, the zoom buttons. Tried various ways over the years, Current setup is probably best option due to Time (Zooming is slow) and memory (needs to work on 32 bit XP with low ram). Possibility of some other ways of displaying graphics exist (including the tool going around in simulate mode) that may make this practical in the future.
2) Yes, can do this. Highlighting the current move in a contrasting colour, and still marking the current position with a circle.
3) Yes, Whenever the Tool pulldown is active, a small window will be open next to it (Covering part of the graphic) showing the full tool description and a graphic like in the Tool editor. I can also align the tool editor with the Pulldown.
4) Yes, but at this point in time, will have to be one out of the fridge.
I will see how I go with the Current Update (Bugs etc Mach4 etc). These May or may not be included, but certainly in the one after.
