Thanks. I found the interface kind of hard to navigate on my 24" screen too. Mainly the the location of the "Menu" is hardest to figure out. The link to source tree is there.
If anyone else is wondering, here's the direct link to repo browser: https://fresh.flatassembler.net/fossil/repo/fresh/dir?ci=tip...
Also, there is a popup menu at left with the navigation links. Although, the repository interface is not very mobile friendly.
Thanks for the report!
