For HTTP flows, render the request and response as side-by-side panels with a draggable divider and independent tab state (new selectRequestTab/selectResponseTab reducers). The request panel carries request/error/connection/timing/comment; the response panel carries response/websocket, with a placeholder until the response arrives. Non-HTTP flows (tcp/udp/dns) keep the existing single-column view. Part of mitmproxy#7789, mitmproxy#7694.
Add a `web_split_flowview` option (default on) so the split HTTP flow view can be turned off in favor of the single-column tab view. It is exposed as a "Split request/response view" checkbox under Options → Appearance, and is settable from the CLI and config file like the other web_* options.

Default `web_split_flowview` to off so HTTP flows keep the familiar single-column tab view unless the user enables the split panels. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A menu group only fits three rows, so a fourth entry in Appearance pushed Reset Column Widths over the group legend. View Options had a free row and already holds the other layout toggles. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

There was a problem hiding this comment.
Thanks @sleeyax! I’ll take a closer look over the coming days :)
Two things/questions:
- Is there a reason why you didn’t implement it the same way as in your first prototype back then? Are you still planning to go in that direction? Since you implemented this as an option that can be enabled/disabled, I’m curious what you had in mind exactly. Do you think this solution works better?
- Since we now have two splitters, I made some UI/UX improvements to the splitter component in #8492. Let me know what you think!
Thanks for your work 🚀

Description
Adds a
web_split_flowviewoption that shows HTTP flows as side-by-side request and response panels with a draggable divider. It is off by default, so the current single-column layout stays the default. It can be toggled under Options → View Options, or set from the command line and config file like the otherweb_*options.Notes on the diff:
tabRequest/tabResponseinui/flow), so switching tabs on one side doesn't reset the other. The single-column view keeps using the existingtab.Part of #7789, #7694.
