It’s been hard to find time to dedicate to this with the holidays and all. So today’s update is not too exciting. But it does open the door to the next step which is.
I added a bar at the top that always shows the focused directory along with a wrench icon. Clicking that icon slides down a palette of tools for the directory: Link (inserts link into TinyMCE), Rename, Upload files, Create a subdirectory, and Delete the directory. Each of those slides in their function. Shown below is the Upload function. It looks like a lot of wasted space, but keep in mind that top area starts off as just the directory name. You can also see what it looks like when a file gets focus.
Nothing too pretty yet. But it’s getting there. The navigation is working very solidly, even backing up the directory tree.
