TL;DR
When chopping down trees, other buildings and blueprints cannot be mined without releasing and reclicking the mine button (LMB).What ?
Similar to the way that you can't mine ores after mining buildings on an ore patch, when chopping trees, you shouldn't be able to accidentally mine buildings or blueprints.(Can't think of any reason this would need a picture!)
Why ?
The main reason I think this would be useful is for when you are placing blueprints over trees in the early game (no robots yet) and the blueprint parks with an 'X' which trees need removing. When I am chopping these trees, the blueprints which I placed under the trees often get removed as well. This means that once I've removed all the necessary trees, the blueprint has large parts of it missing, so it needs replacing in the same spot.That's it! Just a little QoL thing that always bugs me when playing.
