HaliteOS Round 3 submission. Browsers with the best performance: Safari, but it doesn't really matter that much: Running project. Microsoft Edge: Editing (Project not running). Safari: Editing (Project running). Note: Safari is only for Apple devices. I recommend Edge if you have something else. (However, it is sometimes practically impossible to edit the project while it's running). (I didn't test any other bowsers because Safari and Edge are the only ones I have installed). Changelog: Beta 1.1.5: Settings app. Beta 1.2.0: Calculator app; improvements to contrast with text on some accent colors. Beta 1.2.1: Fixed bug with rendering on browsers that aren’t safari; Ui improvements to the volume slider in quick settings. Beta 1.3.0: Added intro. Beta 1.3.1: Added music app (blank) Beta 1.3.2: More progress on the music app; you can now resize windows at the corners. Beta 1.3.3: Perfected window manager. Beta 1.3.4: Work on the music app. Beta 1.3.5: More work on the music app. Beta 1.4.0: OOBE WIP added. Beta 1.4.1: OOBE progress. How to use: Click the logo in the left corner for the button to view the all apps/quick settings menu and the power button. On touch screen put your finger slightly to the right of the volume slider dot if you’re having trouble getting it to slide. Left arrow to delete.
