Would be nice if we got onLBAdded, onLBSet and onLBDeleted events.
I assume quite self-explanatory as to why; for detecting if given listbox/combobox has had something added/set/some entry deleted.

onLBAdded would fire on lbAdd etc, return something like [_control, _indexAdded, _info], _info would return what was added 🤔

onLBDeleted would fire on lbDelete etc, return something like [_control, _indexDeleted, _info], _info would be the deleted index' lbtext, lbvalue, and lbdata 🤔

onLBSet would fire with lbSetText, lbSetValue, lbSetData etc, return something like [_control, _indexSet, _info], _info would be the deleted index' lbtext, lbvalue, lbdata, lbPicture etc that can be set 🤔
