Why did we redesign Thunderbird?

> Currently, Thunderbird faces the problem of simultaneously showing a vast amount of information on one screen and we hope we addressed that.

> Whole work was focused on adding some white space, inserting new typography an equalizing colors, but still keeping in mind branding and character of Thunderbird. That’s why the redesign was based on FirefoxOs Style Guide to keep its identity somehow coherent.

Please keep options open. I really don't understand why people prefer it that way. In the world of small screen laptops, vertical space of screen is very precious to me. I use 11' macbook air on the go and I always have preferred the most compact one line layout. Google also recognizes this and has given three different types of layouts.

It isn't just small screen, but some people prefer and are used to seeing lot of information at once. I am one of them. I am not favoring toolbar or side layouts, I always keep them disable and access everything through keyboard shortcuts. But my requirements are:

1. maximum number of emails on screen at once in one line, no preview pane

2. all email account's folder with highlighted unread emails

I am glad someone is picking up this project, but please keep options open.

I for one very much dislike the three column design. If you're like me and try to maintain "Inbox Zero", and archive everything useless or not requiring a reply in the immediate future, then a UI like this is wasted as there ends up being a very empty column in the centre.

Further, in tiling setups (tiling WM or just having more than one full-screen window open at once on one screen), this approach is even more wasteful, as you may not have 100% of your screen width to accommodate such a UI. TI get that people want more and more of their interfaces to be consistent with the "simple" mobile app design from the last 2-5 years, however I can't help but feel that the re-design provided by the article is more suited for people with vastly different email usages. As another comment has said, keep options open.

This looks absolutely wonderful.

However, Thunderbird seems to be stuck in a development limbo... I legitimately wish that the 'Mozilla Core' approach like they originally created Thunderbird from either needs to be done again from Firefox once proper multi-process via Electrolysis is enabled in mainline, or for them to simply clean-slate a new mail client.

I remain skeptical though, as there simply isn't the resources or interest to pour into Thunderbird as they had when it was first created.

Its worth mentioning that PostBox is a fork of Thunderbird.

This looks nice, Thunderbird was certainly looking incredibly dated last time I used it, but the reason I ultimately gave up on it was performance. Once you have a massive amount of email it can be unpredictable and sluggish.
