Locking up with unknown blockID search

Steps to reproduce

I tried (following the manual) to search and link for a block in an unknown file by typing [[^^ and waiting.

Yes it is going to be slow.
Yes the manual warns of this.
But it took over an hour – and locked obsidian in the process.

Expected result

There needs to a) be a warning b) be a method via which process can be escaped

As a related issue (which would partially eliminate the need to do such searches at all), when one types [[Notename^]] it should display the existing named blocks at the top (with their ID) not simply the list of all blocks

Environment

Windows 10
V0.14.6

Can you just press ESC?

I think it’s a good idea to create a FR for putting named blocks on top of the suggestion list.
