Ways to open / display 2 comics at the same time

I remembered there is an option to run OC with multi-instances in the past ?

But I cannot find it now.

Or there is no way to run electron APPs with multi-instances ?

Previously, when opening a file from the file explorer, I recall that it would launch in a new window. This caused some issues in OpenComic (not due to any limitation in Electron). When OpenComic starts, it reads all stored data (such as config, progress, bookmarks, etc.) from the disk, and from that point on, it works with them in memory. These files are only written back to disk when changes occur.
The problem was that if two or more instances were running at the same time, they would overwrite each other's data, and only the changes from the last save would be preserved.

I'll check whether it's too complicated to make OpenComic periodically reload data from disk.

I'm not sure if there's a way in Windows to force an application to open multiple instances. On Linux, this can be done by middle-clicking the application icon.

Can I open electron APP with 1 instance with 2 windows just like firefox can opeing multi-windows ?

Or a more easy way, open a window, and display two comics at the same time side by side just like beyond compare software ?

In the end, I implemented the multi-instance/window feature bbf6f56. Now files can be opened in new windows by right-clicking on a file or folder (within the application) or by dragging and dropping. The instances keep their storage data synchronized as much as possible.

If you'd like to try it and test to find any bugs, I'll leave you a build from the master branch.
