Config option for sidebar placement (left/right)

[phsb5321]

Hi — thanks for herdr; the agent-aware sidebar + socket API are exactly what I needed for driving a large fleet of coding agents. Per CONTRIBUTING I'm raising this as a Discussion before any PR.

Idea

An additive config option to place the sidebar on the right:

[ui]
sidebar_side = "left"   # or "right"; default "left" (no change for anyone)

Why

I run herdr on an ultrawide with panes anchored to the left and my WM's other docks on the right edge; having the space/agent sidebar on the right keeps everything status-like on the same side and matches a left→right "content → status" reading order. A few tmux/zellij users have similar setups.

Scope (as I read the code)

This looks like a placement flip of the top-level sidebar↔main split in the render layout — the sidebar's width / rows / tokens config and all interaction stay identical; only which side the column occupies changes. Collapsed-rail and the mobile single-column view would follow the same side.

Offer

If you're open to the direction I'm happy to implement it (config field + the layout-order flip + docs) with the default kept at "left" so nothing changes for existing users. Wanted to check direction first per your guide rather than open a surprise PR.

Thanks!

Similarly I would love to be able to put the tab bar at the bottom of the window.
Yes, this is very important stuff 😅

Yeah, this is the matter of habits. Everywhere i can i set sidebar on the right, so that if toggled on and off the text in the main working space doesn't jump.

This seems closest to what I came here to ask as well. I was wondering if it would be possible to split the agents sessions and workspaces panes across both sides so you could have worspaces on the left let's say and the agents on the right.

Something like this?

Apologies for the liberties GPT images took, the general idea is there though.
