If you want some of that back, look into a combination of Boomerang for Gmail (needs a browser extension) and Multiple Inboxes (in advanced tab of gmail settings) I use Boomerang for all kinds of reminders. For me it works better than Inbox did and it was the reason why I went back to Gmail after trying Inbox for about a month. I use a multiple inbox pane "is:starred" for pinning emails. I never really "got" bundles. It was more of an annoyance to me and I prefer manual labeling. The UI: yeah, it's still Gmail...
