Thanks about the menu – I swear I looked.
About the delay, it's not something that I have mentioned personally, but I have seen other people mention it.
It may be tied to not having tags built, but if I select a block of text and delete it, the UI pauses for 2-3 seconds before it responds while it tries to parse/autocomplete.
I see the same behavior if I am just keyboard-navigating the query window (arrow keys) when I move between lines or statements.
