Manage Plugins

Manage the plugins that run inside your generated apps. Open it from ⋮ → Manage Plugins.

What you can manage

Built-in plugins, custom HCJ packages, userscripts, and MV3 Chrome extensions — all on one unified surface.

List & toggle — each row has a switch. On means the plugin is enabled. An app that turns plugins on and does not pick its own list runs this enabled set. A picked list on an app still runs only that list. Plugins you add start on. Built-in plugins stay off until you turn them on.
Editor — create or edit a plugin: manifest, JavaScript, CSS, and a panel.html UI. See HCJ Plugins.
Market — browse the community plugin market. See Publish to the Market.
Browser extensions — search the Chrome Web Store live and install MV3 extensions. See Chrome MV3.
Host style — pick how plugin entries appear (toolbar button / floating handle / menu) and how panels are hosted (bottom sheet / floating window / fullscreen). The floating handle fans plugins out from that spot when more than one is enabled (one plugin opens directly; none still opens the sheet).
URL Switcher — a built-in plugin that stores a list of URLs and switches the current page. Attach it to any app type. The first open is empty; add URLs (or the current page) and tap a row to go there. Long-press a row and drag to reorder. The open page is marked. A duplicate add stays in the list.
Import / export — .hcj packages, .user.js userscripts, .zip/.crx extensions.
