Hey @nickjvandyke!

I'm updating my workflow to use git worktrees where each tab in nvim is bound to a worktree. I was having issues with the plugin because of tab interference. ie. tabs are many to one (opencod). This scopes opencode terms/instances to different tabs.

Do you forrsee merging this (or something similar/better)?

Hmm this is a great point. I have thought about supporting multiple simultaneous connections, at least for SSEs. But it introduces complications like how to select a server when prompting. By tab is a neat idea, but we need a more general solution. (or maybe not? if this only realistically happens in multi-tab workflows)

Yeah this is totally born out of a need of mine. But if someone still wants to control the same session, with this solution, they can still select it using server.select. Though, I think tabs in vim should be thought of as workspaces . E.G https://stackoverflow.com/questions/26708822/why-do-vim-experts-prefer-buffers-over-tabs

In the meantime I can work off of my fork until a decision is made.
