so I've been building my own Gmail for the past few weeks and would like your feedback.

The app you see in the screenshot is what I've been using in the past week and it starts to feel better than the gmail interface.

Just a quick explanation:

- It's conversation-based like Gmail. - Conversations with new emails are on the left. - Conversations may be labeled ... based on predefined filters or manually. - Every conversation stays in the left sidebar until marked "Done" or "Pinned". - Done emails are accessed through the "check"-button next to the "MailApp"-logo. - Pinned emails are moved to the right sidebar. This is basically a to-do list or for future reference. - Both sidebars may be filtered by attributes or labels. - The "list"-icon, next to the filter in the left sidebar, gives you the classic gmail list in the center-panel.

Some technical background:

- It's build with Rails and PostgreSQL. - E-Mail sending/receiving is based on the MailGun infrastructure. - Turbolinks (https://github.com/rails/turbolinks) and Memcache for a speedy UX. - All mail data is saved in a multi-tenant PostgreSQL db and for backup purposes in a IMAP mailbox on MailGun. - Hosted on heroku.

I'm quite happy with the app by now and only go back to Gmail for older emails.

So my BIG QUESTION right now: Would you even consider using the app, in case I'd make a commercial product out of it? Would you pay for it?

Searching HN yielded that quite a few people are looking each month to leave Gmail (for various reasons), but of course there are quite a few gotchas with my approach, especially considering trust-issues.

Let me hear what you think.
