Having the whole client open source is awesome for many reasons, but I think particularly for vetting the security of the server side, open sourcing the app code for the server would be a good next step. There are tons of TypeModels for API endpoints (https://github.com/tutao/tutanota/blob/master/src/api/entities/sys/PaymentDataServicePutReturn.js) but we have no idea what those APIs actually do. :) Particularly with payments, I did not expect payments details to go through Tutanota's API so directly (from the client), and I wanted to see how the server interfaces with the payment gateway.

Thanks for the great product :)

I would like to leave the Google universe, but have so much data in Gmail, that it seems like too much work. If it were possible to transfer my Gmail folders and email, that would be fantastic.

Tutanota needs buttons saying "MARK AS SPAM" and also "NOT SPAM" for when e-mails are in your spam folder that shouldn't be. This would be a very useful feature.

After the update was disgusting and not convenient to work in the phone and on the computer. Why it was necessary to spoil the application working correctly I do not understand.

I've found the spam filter completely useless most of the time, with it marking things such as invoices, shipping confirmations, and account updates as spam. I would be nice to have the option to completely disable it.

Having a few thousand mails in my inbox, I find it hard to scroll down to reach one of my earlier mails. It is very unmanagable..

It should be possible and way more convinient for most of us if you would use pages. For example show max of 100 mails per page and to see the older 100 you can select te second page.

I can't logout!

Life time account for a one time fee, like linux.com has got for $150 (could be less of course)

Privacy.com is a service that allows you to basically create and terminate prepaid credit cards easily. I feel like accepting these cards (and presumably other prepaid credit cards) would improve the privacy factor of paying for tutanota

I wonder why the industry-standard 256-bit AES encryption was not chosen. Today I found that my entire Tutanota email library has disappeared! No sign of it anywhere in my bookmarks.
Browser-based JavaScript cryptography used by Tutanota is considered very insecure. Given what we now know about the extent of the NSA’s assault on encryption standards, most experts agree that AES-256 provides a higher security margin.

please to allow users old layout (on desktop)  ! for some users (maybe a minority of privacy - conscious) new layout sucks, really
as makes impossible to use some modern password managers
and privacy is at core of tutanota values!

not sure , though, how difficult it would be server side is to allow old application links

but for privacy conscious users it will make a lot of difference

Clicking on a mailto: link opens a new tab in which I need to login again instead of opening the composer in tutanota's existing tab.

It would be nice if the app had a setting to change the swipe to left/right-functionality. For example, as in Gmail the swipe settings can be altered between Archive/Delete/Mark read/unread/Move to/Snooze. Except the latter, the other four would make great additions to improving users workflow.

new webmail layout is pretty but hard to use. And since when does privacy mean using customer management companies, google, and other unknown and untrustworthy java/tracking
