Add selectable aspect ratio input + one‑click swap

[fableart]

Hi! I really like the node you’ve made!
It has been extremely useful.

I’d like to suggest a few improvements to the Aspect Ratio control.

Current behavior

The aspect ratio input field does not accept a node input.
Switching between landscape and portrait ratios requires manual adjustment.

Suggested improvements

Allow the aspect ratio field to accept a node input, or even better:
Replace or complement it with a dropdown list of common ratios
(e.g. 1:1, 16:9, 4:3, 3:2, 9:16)

One‑click swap button

Add a button to instantly swap the ratio order
Example: 16:9 → 9:16 and back with a single click

This would be especially useful when switching between:

Landscape ↔ Portrait
Social formats vs desktop formats

Why this would help

• Faster iteration when testing multiple formats, especially on weaker hardware where resolution matters a lot.
• Better usability for portrait/landscape switching.
• More flexible and dynamic workflows, especially when many input images are stitched together in more advanced setups.
• Reduced manual tweaking and overall UI friction which is really important.

I’d be happy to help test or provide feedback.
Thanks again for your great work!
