Settings is at the foot of the sidebar. It is a page with its own address and has a tab for each area.
Profile
On the "Profile" tab you can change "Name", "Email" and "Workspace name", then press "Save profile".
The email here is a contact detail. As the page says: "Changing the email here does not change the address you sign in with."
Theme
On the "General" tab, "Appearance" offers "Light" and "Dark". Light is what you get to begin with.
Two things follow your computer's own settings and have no switch in Vistralo: reduced motion and high contrast. Turn them on in your operating system and the app respects them.
Language
"Language preview" offers "English" and "Deutsch (navigation only)". German is a preview that translates the navigation. The rest of the app stays in English for now.
Text direction
"Text direction" offers "Left to right" and "Right to left". Right to left mirrors the layout.
Dates and times
Dates are shown in your device's time zone.
Checking the connection
"Connection" on the General tab has a "Check" button, which tests whether the app can reach the service. It is the first thing to try when jobs are not moving.
Signing out
"Sign out" is in the account menu at the very bottom of the sidebar.
