This feature is a pretty big show stopper to me as I grill a lot and created a StopWatch face that is almost useless as I normally have my Face Dim Timeout set to 15 seconds, which means I have to constantly tap my watch while cooking (which you can't do if you have heat protection gloves on!!).
The only work around is to set my Display Timeout to 5-Minutes before grilling and then resetting it later BUT THAT IS A PAIN IN THE KIESTER!
If WM could auto-change the Display timeout from the User Setting to 5-min when {swr} [Stop Watch Running] is True and then back to the User Setting when {swr} became False it would solve the problem as tapping once ever 5-min is practical and the auto restore protects the watch battery so it is a win-win solution.
Another thought is for the User to set the Display Timeout to 5-minutes and since WM has a setting that controls the Time-to-DIM if that could be Lua controlled rather than a fixed setting, then maybe when {SWR} is True the OS 5-min parameter could be used, otherwise use the fixed WM Setting for this functionality (ie, 15 sec).
