lettersize in side menus to small

[#1]

Is there a way to enlarge the lettersize of the navigation side menus in LR (and PS) ?

In LRc, i find only: in preference/interface/ choise small or large 

mine is set as large (even if i change to small, nothing changes) but the large lettersize on the largest imac gives me a real measured height of 1,5mm 

Who knows a solution?

Then this would definitely be a question for the other Adobe-monitored forum:

Post to feedback.photoshop.com for:

• Feature requests or wish to add your voice/vote to existing feature requests.
• Demonstrable bug (repeatable with step-by-step instructions and screenshots).
• Crash or error troubleshooting.

To me this seems to be more of a operating system level request, reinforced by your reported testing/result in the Preferences  for LRC.

Sorry I cant offer any other solutions.
