It's your app, so obviously do whatever you want, but I agree with the sibling comment that an immediate mode GUI wastes valuable CPU cycles redrawing the frame repeatedly and will invariably hurt performance Again, since iced is "just rust", you can write whatever widgets you need, although it comes with a long list of built-in widgets (and there are many more built by the community). You can compose views with a bunch of these widgets to get to the UI you want. There's also nothing stopping you from creating a way for users to write widgets for your iced application. The sky is the limit. And I'm singling out iced because I'm a fan, but this should be true for pretty much all robust GUI toolkits out there.
