Okay so this has been an issue I've been having for ages and I'm not sure if the main developers are aware of it or not, but for whatever reason one of the updates either from earlier this year or last year (possibly from the one that created the now fixed issue of not being able to update textscreens) completely broke being able to copy the settings from existing textscreens you've spawned.

Even though when I press R while pointing the toolgun at a textscreen I want to copy it plays the firing sound like it registered the action, but checking the c menu shows that it didn't copy the settings over.

I know this might not have been a widely used feature by most, but I found the functionality and convenience of being able to copy textscreens to be extremely useful for making comics or otherwise keeping textscreen colors and sizes consistent when swapping between different uses, if that makes sense.

(I suppose I might also bring up that the transparency slider for textscreen colors also doesn't appear to actually affect anything, but I don't recall ever really using it before anyway, so I can't confirm if it was always like that or not.)
