Great app! Can't believe this is free. So many tools I've probably used less than half of them. Some things I'd love to see: Dark mode. Please, my eyes! More customization, such as saving multiple custom settings, and custom tool groups. Ability to minimize the tool menu while still using a tool! More integrated layer functionality An easy way to redefine an object by it's position, staying in the same place but detaching from any connected construction

Seems like a powerful package for visually constructing calculations, but it's got a learning curve: you can't just click somewhere, but have to really know what you're doing with that click. Sketchometry (web version) is much easier to get started with, but its drawing tools are put away in inconvenient, non-intuitive fragments, making you click a lot hence-and-forth.

Sorta works. Undo button makes the screen jump around it also doesn't actually undo anything (at least I haven't been able to consistently make it do that). Trying to use compass on a segment followed by a point often doesn't do anything. Measuring angle between three points works but doesn't when selecting two segments. The show hide labels function sometimes randomlly turns everything to show again after working for a while. A plethora of bugs such as these. I would recommend a different app
