Good to know.

Can I adjust a development step while it runs?

Yes. You can nudge a running step by fifteen seconds or update the temperature for the remaining time where the process supports it.

Does Agitate adjust C-41 times for temperature?

No. Temperature conversion is available for black-and-white between 14 and 27 °C. Agitate does not apply it to C-41 or E-6.
