Actually WL still works on my phone with Lollipop, amazing given it hasn't been developed since just post KitKat a year ago.
I unsubscribed from this thread, since with all due respect a thread without a developer's input, with "just" community input, is only at 10% of its potential.
But I still use it - despite it occasionally misbehaving (random Google style indications in blue, and the nav bar appearing), since I still find it useful to hit the power button and see my list of upcoming appointments, unread emails etc.
But I do like the clean Lollipop lockscreen and its notification cards - if WL could replicate the notification cards (or alternatively the stock lockscreen could eg accept a calendar widget), that would be the best solution. I switch between WL and the stock lockscreen, I think I'm about 70% with the staock lockscreen at present
The dev is still active, though he seems to spend his time on his launcher - which is also very good. But as for WL, I doubt many people buy it these days so I fear it's on its way out.
