A high level breakdown of what SQLite is doing, and the time it's taking to do it would be useful for me - e.g. "finding appropriate rows from index, 3.123 seconds, grouping by rows and summing column, 2.456 seconds, ordering column by that sum, 2.987 seconds, taking top 10 rows, 0.123 seconds, joining to table B, 0.927 seconds" would be kind of what I'd be hoping for.
As for features, I wouldn't want much beyond the above. It wouldn't have to be graphical, or need to attach to a running query / SQLite session or anything like that for it to be useful to me. I can probably find most of the "what is SQLite doing" info by looking at the "EXPLAIN" output, but so far I haven't put any effort into learning the opcodes. It seems like that output is a little more low-level than what I'd really want, and it doesn't give me the running time of each phase. Not to say that it isn't useful, but a profiler that fits somewhere in between "EXPLAIN" and "EXPLAIN QUERY PLAN" would be great for my needs.
