Hello!
I found some minor mistakes in English translation of UGENE (version 1.21, 64 bit, GNU/Linux):
1) Search Pane > Annotation Parameters > Annotation Type Drop-down menu (see image below)
Change "Primery Transcript" to "Primary Transcript"
2) Project Pane
When a single unloaded document is selected, the context menu (right mouse button) says "Load selected documents"
When a group of loaded documents is selected, the context menu says "Unload selected document"
I would suggest to write "document(s)" in all cases.
I am sorry if this bug sounds a little picky, but I still felt obliged to report it

Thank you for your efforts!
