Known issues

• it does not resize (you do it manually, it's a freebie)
• the input box might be just too big
• maybe using the key makes sense from a coding perspective, if you want the value....

Trivia:

• This node uses a custom DOM Widget and custom routes.
• It's created as request from a use in the L2 discord channel from matteo/qubic
• not yet in comfyuimanager
• it's created by telling Claude 3.7 sonnet what to do, with multiple round of "it does not work, fix it" i was just too lazy to read the code, so I have no idea what how it does it (just kidding, I still had to read the code to steer ai to do whatever...)
