Our converter PNG export module supports 3 built-in compression levels

Life: X / Y
Mana: X / Y

The strings for "Life" and "Mana" will likely come from the string tables.

    cursor: pointer;
    outline: none;

We moved from Jenkins to GitHub Actions for CI in amethyst/amethyst#2382 -- we wanted to ship that so we can get CI working in general for folks again. Here's a list of other things we would like to do soon. Please comment if you have more ideas!

Each item should have individual issue(s) and/or PR(s) opened for them. Let me know in a comment and I'll add a link next t

I have recently discovered that bevy is quite laggy if debug is targeted even on a simple 3D scene. This is a issue that will greatly affect any larger projects quite soon and even the editor.

Currently is not possible to drop a file or group of files (or folders) from the desktop to a Panda3d window. In my case, as I am doing a media player/file sequence flipbook, it would be a great feature. Don't know if it would be useful for a game, but any kind of application that uses P3D as the backend would have a benefit of it.
