So yes, another step back in the Krecipes usability. SQLite is nice, easy to install, easy to code... but in two (or 3) words: "it's crap". Slower than a cow trying to climb up a ladder.
It's convenient when the lists are small and no strange queries are done, but give it a bit of search work, and it's useless. MySQL could do a query over 3000 recipes in 0.12s and took SQLite 1 minute to complete the same thing.... I can't say that's useful.
