(Feel free to rename the task)
Hello, thanks for new Wikifile-transfer version. I have one request for improvement.

Problem: New Wikifile-transfer requires 4 steps to upload a file (In the previous version, there was only one step). For casual user, it is not a problem. However, for regular user who uploads 10-20 files at a time, its repetitive and annoying.

Suggestion: Remove step 2 (it's already in Preference) or hide it behind a Preference option (e.g. create an option "Do not show Select Project & Language during upload"), so that user who select this option won't see it during upload.

And possibly hide step 4 behind a Preference option as well. (On bnwiki, we don't use same parameter as english, so it has not much use for bnwiki users.)
