1-Had to hunt for the link to my cloud storage, used help to find it.
2-Shows an icon view, which I find useless for file management, Where is the detail/list view?
3-Checkbox select, using single clicks, no modifier keys to make it useful.
4-100gb base amount, In this day and age is stingy
5-For a company that is always touting UIX design, not impressed with the overall utility of the website
It plays more like a sales and promo vehicle than a useful tool.
Ten thumbs down.
Not a feature request. A comment on the downgrade of the use-ability of cloud storage (and general use-ability) of the web site.
So turn it into a Feature Request and become part of the solution.
Even UI comments are best addressed to Adobe via the official Feature Request form so it's in their system and may get read and actioned by Adobe engineers - even if it's not a Feature Request. General dissatisfaction like you've expressed can still fuel change.
Here people will read it but cannot do anything about it so it will sit here - un-actioned - unless an occasional (redundant) "+1" joins the thread.
