One of the biggest holes in web-based collaborative editing software like Google Docs (and Microsoft's Office Live Word Online - I checked) is the inability of the programs to allow the conversion of a block of lower case letters to upper case and vice versa.
You'd think this would be core functionality. Knowing what I do of programming, most languages provide utilities/methods that do this very thing. And pretty much every "local" text and/or document editing program offers this as core functionality.
So why don't Google Docs and Microsoft's Word Online offer it?
Beats the hell out of me.
I got annoyed enough that I set out in search of Google Docs add-ons to bring case-changing capability to the editor I'm using every damn day for work.
The add-ons were not hard to find or install. I decide on Change Case by Alec Tutin.
It does exactly what it's supposed to do, and that's good enough for me. If you use Google Docs with any degree of seriousness, you NEED this add-on.
