I made a new extension for Phabricator / Phorge, it's called Phixator 2.
(it is based on the deprecated Phixator extension that I mostly rewrote from scratch)
This extension is designed to log your work hours on Maniphest tasks (but in a much more useful way than the unusable Phrequent...).
Tested with spaces, integrable to dashboards.
The code : https://github.com/motla/phixator
Let me know what you think.
If you decide to integrate it to Phorge I can maintain it.
