ability to customize renderFileName

[devxpy]

Initial checklist

• I understand this is a feature request and questions should be posted in the Community Forum
• I searched issues and couldn’t find anything (or linked relevant results below)

Problem

The default length for renderFileName is too small.

Solution

Can we please get a way to customize this?

Alternatives

Do this in css/js so the preview text fits the width always

Hi, many people like to use Dashboard but change one small thing and therefor need a new option. If we were to do this every time we’d have a hundred options. The better long-term alternative is to make Uppy UI components composable, which we’re thinking of, but supersede this kind of issues.

If you can find a way to improve this without introducing an option we'd gladly take a contribution, otherwise we can close this for now

That's probably possible, we'd have to put the file extension is a separate HTML element, then we can use CSS to automatically cut the text that overflows.

That might be tricky for accessibility. Semantically the file has to be readable by a screenreader in one go.

Closing this as this should be superseded by #5379
