I’m glad to hear your issue got resolved! And you seem to be quite proficient in using AHP.
Regarding the Toggle Side-Area, I’ll try to work on it in the future. Please be patient. However, I’m not entirely satisfied with PME’s Toggle Side-Area. I feel that the Sticky UV Editor adopted by ZenUV might be more refined. Also, it would be nice if the toggled area could remember the width last used by the user. Wonder if that’s too difficult?
By the way, I’ve been solving your kind of purpose with a different addon.

I’m not actively recommending it; it’s more a matter of preference. I think with a little tweaking of FW’s source code, it could have been used with PME too.
Feel free to ask any questions.
