Hey Mike,
Just suggesting a recolour of the buttons like the menu, settings, voltage view, movement buttons, etc.
I think the default colour would be better if it was the colour that is shown when the buttons are pressed down, and then maybe darken them more when pressed down.
When zoomed into the breadboard, some of these buttons can appear almost invisible, making it really hard to click them.
Example: https://i.imgur.com/eDPYXhH.png
The voltage view button is almost impossible to see in this photo, as the colour is so light.
Thank you
