[FEATURE] offline PWA

[Julmik647]

Problem

I installed OpenCut website as app, but it doesn't work without internet.

Solution

Make an offline PWA that works without the internet.

Alternative

You can also make an app which some users sugested before. Another option is standalone .HTML file version.

Anything else?
