A huge UI update

Happy to announce the new Dots Mesh web app UI.

Let's see what's new in v1.5.0:

• The posts are now stacked vertically on big screens (and centered), just like on mobile. The posts' backgrounds are now dark.
• The mobile toolbar now fits all apps (no more menus).
• The UI is better optimized for phones, tablets, and laptops.
• There are much more icons and helpful texts.
• And so much more ...

The release notes are available at:
