Somehow I don't find 194 MB that bad if the proposed alternative suggests a 197 MB download as "probably easiest to install", but why let details like that let an opportunity to promote your project over someone elses go to waste... If someone with a Debian box handy wants to try how much in dependencies the .deb pulls in...?

The snap package linked in GP is also ~200MB. If you're the kind of person to be frugal with your hard drive, that's cool. But I don't think an electron app is the answer.
