suggestion: sample args needs more settings

[cobalt-a11y]

Sample Args doesn’t appear to have any settings for pixel size of sample images, and also appears to generate 512 x 512 sample size images. When training an XL model, those don’t adequately represent the desired output.

Can we please have the ability to set a specific pixel size for sample images?

And a setting for which folder you want the images saved into would be nice, too. I currently have no idea where my generated samples have saved to.

Samples from the trainer are not really good and won't reflect the real results of your LoRA, for testing is better to use your webui of preference. That said, you can pass arbitrary arguments to kohya scripts in a section of the UI, you can use that option to use whatever argument you need to set for kohya scripts
