I was sent before to adobe mail, somewhere, and they made some improvements, but right now I can't find any mails for that. So..
Right here you can see what Page titles are in the picture and usually they are seen then I click or move mouse onto them. Can you make them movable> I mean that as option you can put them outside the box right under the box? and also as option if they in the box of image they can be seen 100% of the time, not only then you move your mouse onto them.
I hope you make portfolio even better.
And maybe others can also post here their thought about it, so we can improve it and make better together.
Submit feature requests directly to Portfolio's Uservoice where it will be seen and prioritized by the development team. If your idea is viable and enough people agree, it might get added to a future update.
