Highlight-to-copy
Sometimes you don't want the whole message — just one line of it. A new marker button on each message turns on an opt-in select mode for that message alone, so you can highlight exactly the fragment you want. The moment you make a selection, a floating Copy pill appears above it; tap it and just that fragment lands on your clipboard, then the message drops back out of select mode. The highlight itself uses a readable, solid brand-purple so you can clearly see what you've grabbed.
It's opt-in by design: normal messages stay tap-friendly, and select mode only kicks in for the one message you marked — so highlighting doesn't fight with scrolling or the existing copy-the-whole-message gesture.
Footer actions replace the right-click menu
The old right-click correction/delete menu is gone, replaced by a clean footer row on each message:
- An edit pencil — for admins, on Cortez replies — to correct an answer in place.
- A delete bin on your own messages, with a confirm step so nothing disappears by accident.
Surfacing these as visible icons instead of a hidden context menu makes them discoverable and works the same on touch and desktop, where right-click never had an equivalent.
Centered, on-brand modals
The correction and delete-confirm dialogs used to render in the top-left corner instead of centered — a side effect of the chat's flip animation, whose transforms quietly broke fixed positioning for anything mounted inside it. Both modals now render through a portal so they center on the viewport every time, and they've been restyled to match the Neuron panel: deep-black surface, purple borders and headings, translucent buttons, a subtle backdrop blur. They look like they belong to the rest of the app now.
A native-feeling app icon
With GroupGPT now installable, the icon needed to look the part. The old white-sticker icon — logo and wordmark on a white tile — was replaced with a full-bleed purple icon, mark only, letting the OS round the corners so it sits naturally among native apps. The PWA icons were regenerated (and heavily optimized), and the manifest and theme color were set to a rich black so the splash screen and status bar match the dark app instead of flashing white on launch.
Composer polish
The message composer and its toolbar got a tune-up too: the input auto-grows as you type, the tools collapse to stay out of the way, and spacing and sizing were tightened across the board.
Why it matters
None of these are headline features — they're the details that decide whether a product feels finished. Precise copy, visible actions, centered modals, and an icon that looks native are the difference between software that works and software that feels considered. Coming right after the install button, this is GroupGPT settling into feeling like a real app, end to end.
