TaskManager is an open-source application, you can download and install it.
This is the first multi-language application developed completely with MentDB Weak. It is simple but very effective. And above all it is collaborative !!!! If another remote task manager gives you access to one of its projects, you can embed this remote project in your local task manager ... No more logging out, reconnecting. Everything is at hand.
If you want I can install a version for your company in my cloud (or in your company).
