Hi,
I'd like to see an option that allows you to type text with a background color, or alternatively allows you to highlight text.
It's something that's easy to do in Gmail and Word (see attached screenshots) but not possible in Paint.net yet. It looks like it would be easy to add that option because the F8 color option already allows you to select a primary and secondary color.
If you search the forum and Google for this feature you'll find many people asking for this. The only option to do this right now is to add a layer behind it and us a pen tool to add the color, but that takes an extra step and you won't get a perfect straight background with that.
Thanks
JP
