26.2 “Flat UI” Alpha Viewer

The Flat UI Alpha Viewer introduces early work on a refreshed user interface, along with a wide range of stability fixes, performance improvements, and usability updates. This is an experimental viewer intended for testing and feedback as we continue iterating on the next generation of the Second Life interface.

As with all Alpha viewers, your feedback is especially valuable. Please share your thoughts and report issues through our Feedback Portal.

New Features

Interface and Font Improvements

The Flat UI project includes early work toward a more modern interface, including:

• Updated Google Inter font integration
• Improved font scaling and layout handling
• UI adjustments to better support larger text sizes
• Improvements to button spacing, list readability, and selection colors

New Login Screen

Check out our new Login Screen. We've moved login fields to a column on the left with a cleaner and modern interface.

Voice Moderation

Have you heard? We’re adding Voice moderation along with hosting our own WebRTC voice solution! Land owners will soon be able to moderate voice users on their own land. This Alpha viewer will have very limited availability, but we’d love for the community to try it out and give us feedback early.

Who can moderate:

• Region owners and estate managers can moderate voice on parcels configured to use the region voice channel ('Restrict Voice to this parcel' disabled)
• Parcel owners can moderate voice on parcels configured to use their own parcel voice channel ('Restrict Voice to this parcel' enabled)
• If a parcel is owned by a group and uses its own voice channel, any group member with the 'Moderate Group Chat' ability can moderate

How to moderate:

• Go to the location you wish to moderate, and ensure you are connected to spatial voice
• Open the 'Conversations' floater, and right click on any username in the 'Nearby chat' list. If you have moderation ability, the 'Moderation options' menu will appear
• Select the appropriate moderation action, which might include:
  • Mute everyone: mute all avatars connected to the spatial voice channel. Note that this setting is 'sticky': late-joining avatars will also be muted.
  • Unmute everyone: unmute all avatars connected to the spatial voice channel, so that they may speak if they wish.
  • Mute this participant: mute the selected avatar
  • Unmute this participant: unmute the selected avatar

Where to test moderation:

Moderation can currently be tested on any webRTC-enabled region, which currently means any region on the Second Life; Preflight, Bluesteel, Ferrari and LeTigre channels.

For those who don't have a webRTC-enabled region that they have powers over, some public test parcels have been set up at https://maps.secondlife.com/secondlife/WebRTC%20Voice%201/114/225/23

The two parcels are owned by a publicly joinable group, which has been configured to allow for any member to moderate voice chat. Both parcels are configured to use their own parcel voice channel. Click the green orb for instructions.
The main parcel in 'WebRTC Voice 1' uses the region channel, and can only be moderated by the region owner or an estate manager.

Bug Fixes

#5569 Inventory does not update until relog and teleport causes disconnections in Official Viewer and Firestorm

Help Us Improve It

This is an Alpha viewer, and some parts of the Flat UI, Fonts and Voice Moderation projects are still in active development. We welcome your feedback as we continue refining the experience.

As already mentoined in #2023 the new font is unfortunately really bad. It might look good when rendered in a web browser, but in the viewer it becomes much too blurry and is significantly worse to read. A team member seeing a screenshot already commented with "That new font would make me want to alter the sharpness on my monitor"!

Here is a direct comparison between the new and the current font (at 600% zoom):

New Google Inter font:

Current Deja Vu default font:

And this is Noto (originally proposed in #2023 :
