Making these hideable will barely help. At standard screen resolutions, TPT already fits in double scale mode. Doing this will not make it fit in triple scale mode. The simulation area is 384 pixels tall. 384*3 is 1152, which is greater than 1080.

TPT already supports scale 3 if your resolution is high enough.

Doing this would just make the game a lot harder to use for those who turn it on, for no actual benefit.

Just start TPT with scale:3 in the command line. It will *not* fit your screen though.
