Because I wanted to offer batch download also to non Windows users (for example Linux users on Mono framework).
Since SublightCmd is also standalone application (it can be downloaded directly from
http://www.subtitles-on.net/Downloads/S ... Cmd.tar.gz) I decided that it would be interesting to implement this feature in SublightCmd rather than in Sublight.
When you click "Batch download..." button from Sublight this form opens:
As you can see form is really simple and just collects some parameters for SublightCmd (all fields are by default automatically preset).
When user clicks "Run SublightCmd" button form closes and SublightCmd application is launched (command from "Command preview:" is used).
I think this is easy even for less experienced users but at the same time it is also very powerful because it can be used on multiple platforms.
p.s. personally I think that batch download mode will be used only by advanced users
