Feature: Manual tab flagging via right-click context menu #2839
Description
I run a bunch of Claude Code instances across Wave tabs pretty much all day, and I keep wishing I could just right-click a tab and flag it somehow. Like a colored dot, a star, a little icon — anything to let me visually mark "this one needs my attention" or "this one is done, come back to clean up later."
Right now I end up with 8-10 tabs open, each running a different agent or task, and I'm constantly clicking through them trying to remember which ones are waiting on me, which ones finished, and which ones hit a wall. It's the same mental overhead as having 50 unread emails — you just want to star the important ones and come back.
I know there's the programmatic side with wsh tabindicator where tools can set indicators automatically, and that's great for tool-driven status. But what I'm talking about is the manual, user-driven version — I just want to right-click a tab and go "flag this red" or "mark this as done" myself. Sometimes the context is in my head, not something the running process knows about.
Thinking something like:
Right-click tab → "Flag Tab" → pick a color or label (red/yellow/green, or custom text, whatever makes sense). The flag shows up as a small dot or icon on the tab itself. Right-click again to clear it or change it.
Bonus points if the flags persist across sessions, since I often pick up the next morning where I left off and would love to still see my markers.
Basically the same idea as starring emails in Gmail or flagging messages in Slack. Simple, manual, visual. Would be a huge quality of life thing for anyone juggling multiple long-running processes or agents across tabs.
