I've just uploaded the first update to my Gesamtausgabe app this year.

The improvement I find most useful is that the search box now provides hints as you type:

It also automatically diacriticizes certain words. It'll convert "Zizek" into "Žižek" for those of us without a Slovenian keyboard. It does fuzzy searches when there isn't an exact match.

If you're not already using the app, there's more information about it here.  ¶ 8:59 PM
