I was mainly using the cropper next to the snapshot button. With the base model, it would kinda work, but I've got a decent pc so I tried hooking it up to some larger models. Gemma was hopeless and would just try to talk to me instead of properly translating, and more notably mistral kept either spewing out symbols (+kr, ++__++ and such) or saying that there's nothing to translate.
I did have it set to vertical, though I didn't use the drag box much as it kept getting distracted.
Gonna try hooking it up to my best boy DeepSeek to check if it's just the models being weird.
Hoping for your success, this shit is groundbreaking.
