Mouse cursor
Pick one below, or bring your own: paste a cursor page, paste a direct image link, or upload a file.
Pages that work: rw-designer.com has its own rule, and any page whose cursors are plain images is read directly — cursors-4u.com, custom-cursor.com and most galleries qualify. A direct .png, .gif or .cur link always works. Max 256 KB, 128×128.

Liquid glass
Frosts the bubbles, the sidebar, the header bar, the buttons and the sketchboard so what is behind them shows through.
Liquid glass and Frost always apply everywhere, whichever scope is picked above.
How much the glass blurs what is behind it. The refraction that bends the edges stays whatever you set — but past two or three pixels there is little left behind the element to bend. Turns itself off where the system asks for reduced transparency.
Wallpaper
A picture or a video. A link ending .mp4, .webm or .mov plays as video, muted and looping.
Stays on this device — too big for the settings that follow your account, so each machine keeps its own. Up to 120MB.
Show through always applies everywhere. Dim and Blur follow the scope above.
How much of the wallpaper comes through the app itself. At 100% only the bubbles and inputs stay solid.
The messages themselves are not changed
