Tweed is keyboard accessible. All content can come into focus without the use of a mouse; you can control the navigation bar view using the up/down arrow keys, clipboard operations - using standard Windows shortcuts and rotate currently viewed image by pressing ctrl + left or right arrows.

The application has auto layout adjustment. If you resize a window, pane separator moves so that image area is adjusted to 4/3 - the most popular photo proportions. This allows to use screen area in a quite optimal way, that can be especially useful for a compact laptops.
