This might not be technically possible, but I'll suggest it anyway.
You stumble across a portfolio and see, 'You have added this member to your favourites folder' in the top left corner.
Would be possible to click on the 'You have added... and it take you back to your favourites folder, where the person in question is stored?
The reason I ask is because I've personally got 20 odd folders, labeled 'locals', 'mature', 'alt. girls', 'fashion', 'on a promise', etc. It's sometimes tricky trawling through them all trying to locate the model in question. Especially if they've said something fascistic in a forum, got a new boob job, a crazy tattoo or just announced they're pregnant and therefore need removing from your favourites or moving to a different folder.
It's not essential, but it would make life slightly easier.
Add a note to the model's profile stating the obvious.
ie. The model is happy to insert a spear through her nose (!). So you create a new favourites folder called 'Spear' & add her profile to it. Then, you add a note to her profile which starts with [Spear] & then any other notes you so wish to enter.
If the model fits another category in your favourites folder (eg. 'Models from home') then perhaps adding [Models from home] to her notes & adding her to that category would suffice.
So, the model's profile has notes which commence: [Spear][Models from home] Happy to travel 20 miles etc...
Now where did you put her profile?
Just taking time to 'Think' things through more considerately & you'll find a solution.
