Us "developing apps" aren't the ones designing modals - there are teams doing that instead and we implement what they suggest. It turns out that when they ask users of the software I build, at least, that this isn't a common complaint.
The problem that designers are often trying to solve is that there is not enough information that there is a good way to put it on its own page - it's too small for its own page but too large for the table that we'd rather just add another column to.
We have an export button so you can get all the details in excel or LibreOffice or your tool of choice, though. And in a better world, we'd be writing proper desktop apps instead of web applications so that we aren't making stupid compromises like this, but here we are.
- I *want* more details on a separate, linkable URL.
- I *want* it to open in either the same window, or a separate window if I ctrl+click it.
"Subscribe to newsletter" use case is just the worst use case.
