    - a man in a (tuxedo:1.21) - alternative syntax

    - select text and press ctrl+up or ctrl+down to automatically adjust attention to selected text (code contributed by anonymous user)

- Loopback, run img2img processing multiple times

- X/Y plot, a way to draw a 2 dimensional plot of images with different parameters

- X/Y/Z plot, a way to draw a 3 dimensional plot of images with different parameters

- Textual Inversion

    - have as many embeddings as you want and use any names you like for them

    - use multiple embeddings with different numbers of vectors per token
