New UI proposal

Thanks, that's a great inspiration... I was thinking for a long time about a three columns display with folders/tag navigation in a left sidebar, and an ajax loaded file entity form in a right sidebar.
The key features to keep from koken are:
- Three columns display
- Folder/Tags navigation (folder navigation is already done) -> "smart lists". We could add as many as views blocks that we would like here (date nav, last import, etc...)
- Ajax loaded entity form -> maybe the most difficult part
- Inline exposed filters with search input, as a "toolbar"
- Ajax "Add folder" button.
- Thumbnails/Thumbnails List/List button to switch between different displays (different view displays)

I think the layout is not possible with views only... Instead with ugly css positioning... But each columns can be filled with view displays.

Here is a proposal:

Maybe the Lightroom plugin should take place in a specific module... Many people don't use it... although it may be useful for others.

An other useful feature I forgot is a file drop zone... It could be useful to just drag&drop a file in the thumbnail viewer to upload it in the current folder... then edit it with the form in the sidebar.

Here's a start: #1993556: Ajax loaded file summary when clicking on a file

Update issue summary

Add 1996120 issue

Add new issue: #1539134: Better way to upload media in a specified folder

Add new issue: #2030375: Toolbar style exposed filters

I'm still working on this. Here's my latest proposal.
