Why We’re Rebuilding The Thunderbird Interface From Scratch

as a thunder bird fan this is very comforting

tldr: Throughout the next 3 years, the Thunderbird project is aiming at these primary objectives:

Make the code base leaner and more reliable, rewrite ancient code, remove technical debt.

Rebuild the interface from scratch to create a consistent design system, as well as developing and maintaining an adaptable and extremely customizable user interface.

Switch to a monthly release schedule.

Improvements to the UI and UX will continue for the next 2 years, with the objective of creating an interface that can adapt to everyone’s needs.
