Feature request - Adding text labels to circuit/parts of circuit

[Soubhik-De]

Wanted to ask whether it is possible to add the feature of adding text somewhere in the interface or in the circuit itself, so that I can label my circuits / parts of my circuits, so that I can identify which is what.

Thank you for your work!

This isn't really documented well, but there is support for this (as you may notice in the example circuits).

The trick is to create a custom gate with a matrix of "1"; this will show the name of the gate without the box around it so it looks like a comment.
