The completion insight is dramatically less useful in versions since 1.5.5. In that version the pop up completions were very fast, and the focus was always on the "best match" for the table in question. Also, common keywords such as FROM, WHERE, etc. popped up quickly. There current version is so slow that it isn't really useful, and it seems to stop working (3.2.20.09. but also 3.1.07) often.
When pounding out a lot of code, the completion insight for 1.5.5 is really a productivity tool. Is there any chance that a future version will get back to that level of excellence?
