To simplify the workload, I've used MUI Elements and custom stylized them.
At one point I've stopped sending updates to github as I feared for any potential security problems.
The server had a tab for projects - and an archive for them and their files, clients and their credentials. As well as graphs with stats and a very convenient mapbox that would help us find maps that we already have and used, so that we don't waste time making new ones.
In details, the mapbox would create polygons from selected coordinates and point to a project that uses them. Unfortunately the coordinates had to be selected manually on a map - but what's the problem clicking 4-8 times to select a region?
