Identities and signing
Your name and email
Settings › Git & signing shows the name and email Git puts on your commits, and lets you change them for all repositories.
Identity profiles
If you use different emails (work and personal), create profiles in Settings › Identities: a name, an email and optionally a signing key. Then add rules: a profile applies to repositories whose remote address or folder matches. Ramo sets the right identity when you open the repository.
Signed commits
In Settings › Git & signing, turn on commit signing with an SSH or GPG key and choose the key. Ramo uses Git's own settings, so signing works the same in Terminal.
