Hitting micro-size attachment "number" link (See attachment) is difficult.. Does it make more sense if there is list of filenames for better overview and also can reduce number of clics needed to open file as well to make it easier to physically click on it?

Of course it wouldbe better to have drag and drop option there.

In some cases eg, working with projects, opportuntities it would be even better to show x folder content in Sharepoint (can manually link e.g. opportunity or projecrt folder)
