Batch convert - preview
there are few inconveniencies in file browsing in Preview (Actions tab):
- file name is not visible, eg when processing similar images
- not possible to jump to the first/last file or exact file
- inactive progress bar takes too much space and provides no info
Suggestion
A
- filelist
 - add current file name
 - add first/last file buttons
- zoom
 - move zoom controls to the left horizontal bar
 - move zoom value to the top
- 'Remove from filelist' command
 - add command to the context menu
 - add shortcut (Del) works only when any control in preview group is selected/focused
 - change icon: X (delete) → − (remove)
- Before/After
 - remove inner borders of tab control to save space
B - preferable
same as A, but
- move all controls inside Preview group
- filelist
 - add filelist scrollbar
- Before/After
 - rework tab control into single 'Swap' button to save extra space around image
- progress bar
 - move it to the top, inside image
 - make it narrower and visible only when active
- (optional) image overlay
 some information can be displayed as overlay (see GmicPlugin)
 - move current state (Before or After) to overlay (top left corner)
 - move current zoom value to overlay (bottom left corner), show it for 2-3sec after zoom change
Example
- files controls
- preview
