how to selectively show indices as developer One can choose to &quot;show indices&quot; of the vertices of a mesh when in edit mode.  However, when there are a lot of them, you can no longer read individual ones, it becomes a giant cloud of indices.  I would like assistance in coding an add-on that would allow one to add a boolean value to indices that you define (if defining them in python), so that when, as developer, you request to &quot;show indices&quot;, only those indices that you've indicated you are interested in are the ones that get marked.  Perhaps this functionality exists already?  If it doesn't, help in finding the code of the existing functionality would go a long way to helping determine how easy or hard this will be..
This is not directly, what you asked for, but it may help anyway:
Only the indices of selected vertices are displayed. You may write an add-on, that selects only the vertices with certain indices to achieve what you want to.
