Feature request: Autocomplete suggestion for current date or datetime

[JohannHansing]

This is a feature request/ idea.

I often verify queries on some arbitrary recent date or datetime. It would be neat if typing e.g. '2021- would autocomplete to the current date (e.g. '2021-08-11') or the current datetime. Or perhaps first the current date, then, if one continues (``'2021-08-11 `) autofill suggests the current datetime.

I could probably implement this myself since I am familiar with python. However, I first wanted to ask whether such a feature even makes sense and of course if you are even interested in having someone "external" like me attempt this.
