You are right, the 6 second limit is on the low end. Ther is also a timeout for general inactivity which is currently set to 60 seconds. I want to make them both configurable and provide better defaults.

The storage of arbitrary secrets is definitly on my todo list.

As for the git integration i do not see the point of having it. For someone who is able to set up a remote git repo, it should be trivial to use git for synchronization, even without "git integration", since everything is stored in a single file.

I have not yet looked into browser integration or clients for mobile platforms, but maybe there is a way to integrate with existing apps/extensions.
