How to have mutiple projects?

I suppose every time I open a new tab, it’s the same project I saved. So I don’t think I’m able to work on other ones other than the previous project I’m doing. Also even if I saved them, like for a file, it won’t let me open it cause it’s not supportabler for my Chromebook. Is there any way I can work on more than one project?
This is the newest version of Wick Editor.

Are you trying to open the actual saved .wick file? Because if you are, it’s not gonna work.
You can open saved files by clicking the open button in the top right corner of the editor, then selecting the file from there.

Let me know if this is what you did.
