Make Marker Size freeform / spin box input about freecad HOT 5 CLOSED

@Oozlum it maybe best if you look at how the last size increase was done to explain why a spinbox isn't applicable to the current solution, see 00826ab

@Syres916 thanks. I think the implication is that manually changing my preferences to 30px only worked by coincidence, as 30px was already implemented?

I think my question would be then, if that commit implemented 20, 25, and 30px sizes, why aren’t these available to select?

Being specific with my wording so as to reduce ambiguity, using:

30px markers are easily to select with a Pick Radius of 20px but you are maybe struggling to select them with the default Pick Radius of 5px. Pick Radius is available through Edit > Preferences > General > Selection

Obviously 0.21.x doesn't have the new sizes available as they are classed as a feature enhancement and the general rule is only bug fixes are backported from the dev (main) branch to the stable branch.

Thank you. It isn't so much the selecting that was the issue for me, rather that with the smaller sizes the pre-selection wasn't as clear. Either way, 30px is fine for me, so I'll close this given your comments on its implementation.
