Feature Request — Custom scrollbar width / DevTools access in Codex Desktop

[kawaiies]

Hi Codex team,

I use Codex Desktop daily and love the experience. One small but persistent
usability issue: the scrollbar in the chat area and sidebar is very thin
(scrollbar-width: thin), making it hard to grab and navigate through long
conversation histories.

Suggestions (any one of these would solve it):

1. [Easiest] Enable the --enable devtools feature flag.
   Currently codex app --enable devtools returns "Unknown feature flag."
   If enabled, users could open DevTools with F12 and inject custom CSS
   without you needing to change any UI code.

2. [Nicest] Support a desktop-plugins/ directory like Hermes Desktop does.
   Users could drop a plugin.js file that gets loaded on startup.
   Hermes already has a clean working implementation to reference.

3. [Middle ground] Add a "Scrollbar width" setting in preferences.
   Three options: Thin / Standard / Wide would be enough.

For context, this is already trivially solvable on Hermes Desktop via its
desktop-plugins system. Would love to see Codex Desktop offer similar
extensibility.

Technical note: Chrome 121+ blocks ::-webkit-scrollbar { width } when
scrollbar-width: thin is set. The workaround requires overriding
scrollbar-width: auto !important first, then setting custom
::-webkit-scrollbar rules.

Thanks for considering!
