- default windows view and layout is too small, also preview is too small, but I think this is a bug
- hide scrollbar - enabled
- quick slideshow delay, currently it's just 500ms, I'd change it at least to 2000ms
- show hidden files and folders - disabled (better for new users IMHO)
- view info: {Directory}{Filename} Tag: {Tag status} - I think directory is quite useless info, i'd add rather more info, it's always easier for user to delete what he doesn't need, I suggest this:
<File Index> <Filename> <Format (short*)> <Size KB> KB <Width>x<Height> ((<Date Taken [A d.m.Y H:M:S]>)) ((<Make>)) ((<Model>)) ((<Zoom>% )) ((<Tag status>)) ((<Rating>)) ((<Color label>))
Or lite version without rating, color label...
* , not implemented yet

- the same for browser tooltips: <b>{Filename}</b><br>{Modified Date}/{Size KB} Kib - modified date is useless IMHO, EXIF date taken is much more important these days
- last but not least - thumbnail labels - at least replace EXIF description with date taken, perhaps also format name with image width x height. My options (from Win version):
Filename
Custom 1: <Date Taken [A d.m.Y H:M:S]>
Custom 2: <Width>x<Height> - <Size KB>KB <Model>
- double click - fullscreen <> browser | fullscreen <> viewer **
- middle click - browser <> viewer **
** Most video/movie, TV, satellite, web-tv players use double click to enter/exit fullscreen.
