Grid and background image in preview

[cnieves1]

Hi,
First of all, I like to congratulate you for this wonderful tool!

I'd like to share with you a couple of thoughts, just in case you find them interesting...

Sometimes I get a label layout, designed with another more general software.
Transforming it into something I could feed to a ZPL printer means several iterations: ZPL code, preview, compare, change, and back again.

In the label preview, I can think of two features that would speed up that process a lot.
If I were able to set a background image, to compare the printed label with the desired label, and a grid (in dots/mm/inches) to check dimensions, then I think I could do the above process even with my eyes closed.

If you could add that features, I'd be very grateful!

Thanks in advance,

Carlos
