Rated 5 out of 5 stars
Definitely my new favorite TB theme. Although I favor (well thought-out) dark themes since they give me less eye strain, I find the use of light greys in Silvermel quite soothing. Good job.
The icons are good, but I wonder if the theme would look even better with another set (not a deal-breaker for me, though).
Would love to see a "Jetmel" or "Obsidianmel" version of this theme... in other words a dark theme, since the few existing TB dark themes are not very attractive IMHO (although Cutebird, which was my default theme until I discovered Silvermel, comes close to that ideal more or less).
