Variables in search query syntax?

Here is the request: can you, please, introduce variables in search query syntax? I’m especially missing the %title% (note title) variable. There are other great possible variables too: uname (user account name), date (current date), time (current time), ctitle (current note title) etc.

This will allow us (for example) to (auto)insert TOC/MOC into notes:


or color the current note differently in Graph:

Color groups:

What do you think?
