1 . How can i setup CUSTOM SIZE ? I mean not by write for every image.
Custom size settings should be in Preferences - or more sizes avalible - sometimes i need only small and quick previews 960 x 540 for example . Maybe CUSTOM and CUSTOM 2 SAVED
or simple > ( check attached )
2 . On export should be choose size BY IMAGE or ALL OVERWRITE ( i mean that you can export all in one size no matter what you setup by image )
