I've wanted to work on a few tiny tools in Rust, but so much of my workflow relies on proper clipboard support that it's never worked out.
Maybe some day I'll have time and energy to work on this, but the issue seem to come from underlying libraries providing abstractions that just don't allow properly inter-operating with the clipboard.
Of course, this isn't a problem for an IRC client, since you can't send images or anything like that anyway.
This seems to have a form of drag and drop in the demo gif.
Consider this idea: Most people who use a table class in a GUI framework assume it is essentially infinitely scalable (myself included!). I am talking about millions of rows or thousands of columns with all kinds of silly widgets injected into individual cells. It is a crazy hard computer science problem to solve. I would not doubt there are many PhD thesises written on the topic of fast, scalable table widgets.
Beyond desktop GUI toolkits, people have tried to do the same in a browser (HTML/CSS/JS). Have you seen AG-Grid? Woah, it is unbelievable how much goddamn data you can squeeze into that widget. Most Wall Streets web-based trading apps use it one way or another. It's just so hard to beat. Ref: https://www.ag-grid.com/ There must be 1,000 person years of optimisation sunk into that implementation.
The feature list is really impressive: https://github.com/iced-rs/iced

Wow, wow, wow: Keep up the great work.
One of the rendering engines is Skia by Google. This library is sneaking up fast on us...
