There is one thing I always loved about Textpattern:
The language handeling.

You just had one list with all available languages and an "Install" link. After you clicked the link the language was downloaded, installed and ready to use.

ProcessWire handles language install a little different: There are language repos with json files containing the translated strings in it. To install a language you would have to create it manually (insert a name, add a title, etc.) and upload the language files afterwards. That's not what I would call "simple". So I made a module: LanguageInstantInstall

It adds this great Textpattern feature to Processwire and makes it a little easier to install new languages. Read more about it.

I did some bugfixes on it today and uploaded it finally to GitHub. Maybe it even becomes a core module - who knows.
