Created attachment 2939 comparison some ideas for thunar 1. sorry for my english(= 2. Remove the border around thunar it makes the application fat and has no use. Compare thunar with konqueror konqueror is borderless an looks very slim 3. the most of the time you don't need a menubar for filebrowsing so make it hideable, like the terminal 4. Why the Toolbar has a home link? you can find it in the Sidebar, under go to or with ~. so, its not really necessary for file browsing 5. Why not use a comboboxentry instead of a entry+button as adressbar? 6. the settings and properties should wider than higher, i think it would look better
