I'm a newbie here, it's day 1 for me, but here are a few of my first thoughts:

I would love to add todos in the web interface.
I try to take at least one day off per week, so I'm assuming my longest streak will be 6 days.
I didn't know that wip has a product page and would love to see more features around this part.

But that's my first reaction. Obviously the feedback of long time users is more valuable.

I don't let external links open in a new tab, so the user can choose the prefered behaviour.
