SeizeControl - App Themes · published · build 23274705
This update adds richer App Theme backgrounds, app-wide zoom controls, cleaner File Explorer settings, and a set of smaller fixes and polish across themes, hidden files, and the Pen plugin.
App Themes can now use images, GIFs, videos, and website URLs as backgrounds across official and personal themes. Theme panels now include a background source selector, media picker, website URL input, fit controls, a visibility toggle, and video volume controls.

You can now make the whole SeizeControl interface larger or smaller from Settings, with keyboard shortcuts for quick changes: Ctrl +, Ctrl -, and Ctrl 0. This is useful if you prefer the app UI to scale independently from your screen resolution.
App zoom:
Grid view now has an option for where custom folder icons appear. You can keep them as a badge in the corner, or place them on the folder flap for a more integrated folder look.
Comparison:
The back button in Plugins and App Themes now returns to the More page instead of leaving that section entirely.
File Explorer settings have been reorganised into clearer groups, so related options are easier to find.
The File Explorer root folder no longer shows a misleading chevron icon, making the file tree more compact as well.
The Cyberpunk theme has been refined, including cleaner styling around native checkbox and radio controls.
Hidden files now match Windows File Explorer behavior more closely, and hidden files appear faded when you choose to show them.
The Pen plugin now enters drawing mode more reliably, and line, rectangle, circle, and arrow tools show a preview before the shape is placed.
Theme sliders now stay responsive while adjusting values and no longer jump back to earlier settings during rapid changes.
Themes can now opt into the shared background host for local video and website backgrounds, while still using normal CSS backgrounds for images and GIFs.
Host controls:
--app-theme-background-kind: use media or video for video backgrounds, or website for website backgrounds.
--app-theme-background-src: local media URL from the media picker. Videos are rendered by the host; images and GIFs should still be applied by the theme's CSS background layer.
--app-theme-background-website-src: website URL using http:// or https://.
--app-theme-background-fit: cover, contain, or fill.
--app-theme-background-visible: true or false.
--app-theme-background-volume: 0 to 100, for local video backgrounds only.
Important limits:
Host-rendered video backgrounds must be mp4, webm, mov, or m4v files. Videos autoplay, loop, and play inline; there is no theme variable for looping.
Website backgrounds are sandboxed, non-interactive, and best-effort because remote sites can block or behave differently inside iframes.
Website volume is not app-controllable, and themes cannot enable privileged permissions such as camera, microphone, geolocation, clipboard, payment, popups, or top-level navigation.
