It's super annoying as GM when using thin or small tokens on the map: You're far more likely to resize the token than grab it. --> A token's right-click menu should have a "Lock/Unlock" toggle command. When Locked, re-sizing is disabled for that token; resize handles are not present. Toggle Lock/Unlock again to revert. Default is Unlocked of course. I've done a search, and this is a known issue with requests to fix this going back years. Only workarounds are API scripts that are partially-functioning kludges. Token Size Lock should be a standard Roll20 feature.
