Kirbydogs no name here lol (ID: 000000d7c62e5642) Voted 5 ★ - Updated 08/02/2022 It's great, but I found one problem. If the extension is on, and your in Fullscreen, the scrollbars won't disappear.

Hoang Le Vu (ID: 000000a2b168ec5c) Voted 5 ★ - Updated 04/30/2022 Rất hữu ích, sài ok vl :))

Leo (ID: 0000009912f8539c) Voted 5 ★ - Updated 08/17/2021 This is SO, SO, SO cool! I absolutely love how you can edit the positioning in there!! Are there plans to add waveforms/sound waves to the editor? That would be extremely helpful!
