We’ll likely stay away from the old folder metaphor, in a pinch items such as files can be grouped by sections.

Our thoughts… Files that are important should not be hidden.  If someone is working with many files, perhaps they are working with more files than necessary, or there is a better way to manage the information.  We do have plans to add revision support for files.

Sections could work, but since a section takes everything below it, until the next section break it isn’t all that practical if you have items that you don’t want in a section (unless I’m missing something about sections).

For our business we have lots of files per customer so it’s not a case of working with more files than necessary. A typical example is that we store floorplan drawings for each of our customers. A typical customer will have anywhere from 5 to 20+ floorplans (one for each of their office floors in their building) so it would be nice to always have the most current version of each floorplan in the Customer Contact section, but have them all grouped in one folder.

We currently store them on our server, but using Solve to store them would then allow the customer to have access to them quickly and easily if and when they need them
