OT: I've been trying recently to find something that works like the old Google Inbox project. Inbox was the only time I've ever reached inbox 0, and it annoyed the hell out of me when they cancelled it. Has anyone seen/used anything that comes close?
Readdle's Spark[1] has been my Inbox replacement since Google killed it. It has pin/snooze functionality and a similar concept of grouping emails by category and letting you easily mass mark-as-read. Plus, you can connect multiple email accounts rather than just being limited to your Gmail account. It's also nice because you can have a "team"; my wife and I use it to share important messages and help each other draft or review emails. They have really nice apps for Mac and iOS, too.
I've been using Spark for years and love it. Snoozing is great though it is not an exclusive feature any more. I believe there are some privacy concerns with Spark but I'm very happy with it overall.
You can effectively get inbox back now. The guy at Google who made it set up on his own and made (very good, paid) browser plugins to restore functionality.
Shortwave, imho, comes really close to the old Inbox experience. I'm not sure that I recommend it, but it was good when I was trying it out compared to vanilla Gmail.
