We’re huge fans of Adobe Photoshop Mix for the iPad, but as much as we like it, it had some rough edges.

Our own Charlie Sorrel called it more like a proof of concept than a proper app, that needed some work before it became truly indispensible.

A new update to Photoshop Mix has just helped polish some of the app’s rough edges. The new version adds support for a much-needed Undo/Redo function, as well as local saving, Dropbox support, swapping images, and more.

I was all set to pull the trigger on Adobe’s Creative Cloud Photography plan, which gives subscribers access to Lightroom and Photoshop as well as Lightroom Mobile for the iPad and iPhone.

After all, it’s just $10 per month, right? (or €12.29/$16.71 in the EU). That’s about what I spend on Rdio, or Dropbox, and I get Lightroom on my frickin’ camera.

But I decided to hold off and see if one huge doozy of a design problem is fixed before my 30-day trial of the service finishes up. This will also give me time to check out the amazing new Adobe Photoshop Mix, which is what Photoshop for iPad should have been all along.

And the little problem that could be a deal-breaker? You’re gonna love it…
