Sketcher: Select constraints near geometry or other constraints

[maxwxyz]

Is there an existing issue for this?

Problem description

From the FreeCAD Day 2024 Complaint Session:
Constraints pointing and clicking might not select correct constraint.
Discussion:
Sometimes in Sketcher when having multiple redundant constraints I can see the constraints I want to remove visually next to the line but I can't click it because there are some other constraints near it, and it has reordered them and it doesn't know where I’m clicking. So pointing and clicking to a constraint does not select that constraint.
There is a unclear selection priority when multiple elements are within a certain radius (or it is non-existent). There is no possibility (like e.g. in KiCAD with a long click) to get a list of all elements under the mouse cursor to choose which you want to select.
Often it just can’t find anything, it doesn’t select anything, and then I have to zoom in a lot.
