Having tried out Special:InvestigateBlock, while it is more convenient than using CheckUser and blocking from there, there are some options that should be introduced to the interface.

• Changing block times: IP block times seem to default to a week without an option to change it. While that is usually okay (and I would be happy with a default being in place), I would've liked to change the duration. I assume that blocks for accounts default to indefinite?
• No "soft"/"hard" block options: I could not enable account creation (rare usecase, to be fair) and I could not make an IP block apply to accounts too.

I wanted to conclude this by saying that I appreciate the intentions with which this was made. Mine are probably rare-ish usecases. Thanks!
