No problem!

Most of what was needed was already integrated in the current system. For all those projects, we used a home-compiled calligra, not as installed by any distribution.

Hm, there were some huge optimization enabled for the Harmattan Office project. I'm not sure where Nokia left the git repo, but you can get it from http://www.valdyas.org/~boud/office-tools.tgz. I think the sheets canvas has an option to enable multi-threaded rendering, but I'd need to dig in again to figure that out.

Yes, we need to resolve that. Unfortunately, Marijn is now in the USA and at Google, I'm not sure he's got the okay to work on open source already. Stefan Nikolaus has disappeared some time ago already. Let's see what happens. If all else fails, we'll replace the dialogs with new ui files.
