Yes, that is the consensus of why Qt sucks - it's a massive framework that tries to do everything at the same time with a massive toolset of in-house libraries. This is inherently tied to the revenue model of the Qt Company - sell custom modules that work well with the Qt ecosystem at a high enterprise-level price. I also wish to just use the "good" parts of Qt but I can't, since it already has a massive QtCore as its dependency.

However, there is still no cross-platform framework except for Qt that can actually do the most important things that a desktop framework actually needs: an actual widget editor, styling and theming, internationalization, interop with native graphics APIs (though I have gripes with their RHI system), etc. That's why I'm rooting for PanGUI (https://www.pangui.io/) to succeed - it pretty much completes all the checkboxes you have, but it's still WIP and in closed alpha.

Yeah, but at that time I thought this was at least better than wrangling with Qt / QML. You can write the core application logic ("engine" code) in C++ and bind it with Dart. There are already some companies I've seen gone a similar route with C# / WPF.

As far as I can tell, PanGUI is a drawing library not a graphical toolkit. Its primitives are geometrical, not widgets. Its showcase is an audio app, which is as far away as possible from a boring productivity application that I'd like to do.

In my university days I was very much into GUIs, and I've written apps with wxWidgets, plain Gtk 1 and 2, GNOME 2, Qt, Tk, GNUstep and even some fairly obscure ones like E17 and FTLK. For my tastes, the nicest ones were probably GNOME2, Elementary and wxWidgets. Especially GNOME2, which had a simple builder that let me create the basic shell of an app, with some horizontal and vertical layout boxes that I could later "hydrate" with the application logic.

They say it's in beta and it seems anyone can sign up for the beta.
