I love how easy Dropfiles is to use, and I have replaced Docman with it for at least one client. BUT, I'd love to see some other options:
#1 a front end component view, so admins can manage files from the front end. Asking them to edit an article and then click in the text editor and then finally edit the dropfiles entry is a pain (and it didn't work in my tests).
#2 An alternate plugin for linking to single files that's stripped down. I modified the plugin code myself for the tree template so that if I choose a single file (and the category is set to tree), I get just a nice icon with the text next to it. This is much cleaner than a giant block with lots of file info.
#3 I'd love to see the file name or the category name on the giant placeholder that is in the text editor. Right now, if I make an article and I link to a few single files in that article, I get a bunch of giant placeholders but no way to know what they actually are until I click on them and then click the dropfiles editor button.
#4 I'm not sure if this is already in there, but I want to be able to set the default template (in my case, Tree) so that everything is set to tree all the time unless I change it for a specific category. Right now I have to change every single category to Tree manually and it's getting old.
Overall though, I really love this extension!
