First version of color selection points
Created by: bolmsten
This PR gives colors of selected points in this case red (to be discussed). While developing this I encountered a number of questions that need to be answered, so I will put them here for disucssion.
- What color should a selected point be?
- Will it be the same color for a point that is not saved but selected as a saved point.
- Can one create a group with a saved point and a tmp point? And how does one see the difference between this and a group with only saved points.
Test out the PR if you can and give feedback, there is a lot of cases to consider and I have probably missed a few.
