One of the things I hit is that there is no way to trigger an "open folder" dialog. It gets mapped to "open file" instead. The correct hooks exist in both WebKit and in GTK, but not wired up in WebKitGTK. I think the fix would be quite minor but I looked into what is involved in raising a patch and decided to leave it. There are a lot of minor paper cuts like this.

I did hit a couple of CSS or rendering quirks, but the rendering perf also seemed noticeably poor, and that's harder to live with.

Recently vibe coded this https://www.rominabox.app/ and also loved Tauri for the "builder" part of it! What a pleasure to work with.

Granted, it's very simple, but I felt it was a breeze.
