I'm talking about on the order of ~1Gb data used in the view. I have data from scientific instruments, when an interactive view is fully zoomed out showing all of the data at once I basically have to have it all in memory to maintain decent performance. Here's a video of the app in use: https://www.youtube.com/watch?v=EY9wvd6ckb0
In an ideal world it'd be cool if one could make a TopComponent with an instance of Chromium or whatnot inside and be able to use cool stuff like D3.js inside. I also constantly find myself struggling with creating forms in swing that are just used to represent parameters for command line programs, it's always tricky for me to make everything aligned and resize nicely. Form validation is yet another pain in the ass, especially when it comes to the visual part of notifying the user what's wrong in which part of the form. It would be so nice if all of this could just be rendered as a simple html table with my choice of js validation framework and that I didn't have to think about layouts etc too much.
