Please, please please, create a view as thumbnail option within folders. Home page shows most thumbnail images, however when opening a folder reverts to list view. This function is critical for users to identify docs quickly... windows had feature since version 3.1, Apple has feature, Google has feature.... yet not available to Adobe? Premium cost for Adobe throughout years, yet the fundamentals are lacking for your customers. Your older free version of adobe reader had funtion, but for your paying customers we loose feature? Help me if I am off base...
