I realize you don't get rulers - guess because you don't do tasks where they're useful.  But if no one used them, devs wouldn't put them in & continue doing so for yrs, decades.

I agree, lots of ways to do what you're suggesting - maybe better than rulers.  I didn't want to suggest difficult options.

text showing you the exact size of your selection at the bottom

Well... 1) the #s at screen bottom are usually small (in this case - very).
2) (I suppose) many consider looking at a crosshair on ruler ticks as taking less concentration than reading 2 numbers.  Just looking at a line - if it's lining up, vs reading 2 #'s.  From a "theory of learning" standpoint, the latter takes more concentration.

I'd like to see (in any editing app) values for crosshair location, area, etc., in big, red #s - right above  current position or image.  Then disappear, once done w/ selection, moving, etc. (& then just show at screen bottom, as usual).

What's an "optional top pabel?"  Label? Parable?  Pablum?  Pablov?  Table? :D  Any of those would be great for showing cursor position, starting & current cursor / selection line position, area; esp. table, label, pop up box w/ values, etc.  Not sure about a pabel.

Figured if I couldn't get the font size at bottom of main GUI increased (cursor selection position, area,...) or Options UI, had no chance for something like you're describing.  If you want to bounce ideas off me, that's fine.

Many editors (even simple image viewers w/ some cutting / cropping function) have grids, as well.  With varying capabilities.   They're also useful for certain things.  I have > 1 wrench & screw driver in my (real) toolbox.  I can barely pick it up.

CMPM - uh, I already gave some examples of how they'd be useful.  If you don't like rulers, you don't have to see them - they're off by default, so they won't cause blindness.  :)  There are other tools in SSC that I've rarely used - I don't berate others (that's right - I said it  :D) when they talk about tools or issues, that don't concern me.  Be a tiny bit tolerant.  

How can I post an image or created icon, or anything I used a ruler on (or many other functions ), when evidence of using a measuring tool, grids, & many other tools disappears after finished?  That goes for a 100 tools in a 100 apps.  No one uses rulers present in 100's of apps, incl. screen caps., editors, drawing, PDF, word processing, on & on??

I ain't isn't familiar w/ screen calipers, but thanks.  Rulers on image editors (even pdf readers, word processors - w/ image pasting ability) aren't exactly "high tech."  I only gave SOME uses, not that everything had to be a matter of + / - 0.05 px, for them to be useful.  :)  It doesn't have to be for microscopic applications.

You're correct, most rulers (that end at 0), have offset #s.

Thank you very much.  Many that use the feature (in that way) will appreciate it.

My intent is NEVER to say SSC isn't an overall good app or to insult / inflame anyone.  But NO app, anywhere, is perfect.  That's why they're all constantly "improving" - at least changing.

Sometimes, seems certain apps' "improvements" are a step back.  :)  Sometimes, devs are working w/in limitations - no fault of their own.
