Anyone have a good resource on monorepo design and workflow? I find myself keeping supporting projects up to date in their own branch and then cherrypicking commits from random other projects' dev branches, where random commits happen to improve a non-focused branch. But the commit history in my main dev branch gets muddied with these random merge commits (merging changes that have improved the secondary projects). In other words, merge commits aren't necessarily indicative of critical chronological moments. But they muddy up a nice chronology of development commits. I could use some ideas on the architecture of monorepos...
