It would be nice  to view and edit DNA sequence files created with SnapGene.

Hello,

Unfortunately, we do not have such plans in the neares future. I could give you a little trick - despite the fact that this format is binary, it has sequence representation as text inside. So, if you opened a file of this format in any text editor, you could copy a sequence, paste in into UGENE and UGENE opens it as a sequence. Unfortunately, there is no direct way to export sequence annotations, but you could process some analysis like restriction enzymes searching, primers picking, etc.

Also, I could tell you, that we can implement this format regognizing in UGENE in terms of commercial support. If you are interested, please, let us know and we send you details.

Best
