I haven't used Thunar, but I wrote a GTK+-based file manager that was fairly popular Way Back When (late 90s, early 00s perhaps) called "gentoo".<p>Congratulations for landing a GSoC gig of course, that must be awesome. A project I worked on ages ago almost tried to apply, but all we got was the t-shirt. :)<p>My take on the ideas:<p><i>Undo/Redo</i> sounds like a lot of work, at least if it is going to be integrated well and supported for many operations. Again I don't know Thunar, but I guess you're going to have to figure out if there is a command abstraction internally, and start storing a log of executed commands so that undo can compute the reverse action. I guess some commands ("delete" comes to mind) are really hard to undo without rather intricate changes such as inventing a trashcan and moving things there, and so on. It seems clever to start with this, it's a real heavy-weight.<p><i>File counts for folders</i> sounds strange; if there's a size column I would of course assume it to show size for folders too, not a completely different thing like the number of contained objects. In gentoo there is an explicit command ("GetSize", if I remember correctly) that recursively computes the size of a directory, and replaces the on-disk inode-level size of the directory with that. It's explicit since it takes time (gentoo is not multi-threaded or async, so it will block) but on modern disks it will be very fast.<p><i>Picture-specific view</i> sounds like a great idea, especially if it's possible to integrate it well so you don't have to re-implement a lot to get access to basic file management commands for that view.
This is great to hear! I use thunar mostly because it doesn't force me into tabs like the "big name" file managers all seem to do. It is snappy and stable and does almost everything I want.<p>The undo feature will be a really nice touch.
Right mouse drag. Please. If you want a demo, fire up Windows, grab a file or folder with the right mouse button and pull it somewhere. When you release the right mouse button you get a menu, ie: move, copy, create shortcut etc. Even after using Linux almost exclusively for 15 years I still miss this.
