The use of float here should be safe, I think, since this is a UI-only thing?

Yes, but I'm not sure what problem is being solved, Maybe some examples?

It wouldn't sort properly because some vehicles had more power than running cost. Just check with any set that adds vehicles with more power than cost. Let me find an easy example.

Here you can see that according to the sorter:
4602/1915 > 5871/2168
aprox.
2.4 > 2.7
Which is not true at all.

Same list sorted properly.

Also, please squash your PR down to one commit when you're done.

As you can tell i am kinda new to contributing to projects in github, and more so to this one. How would i go about squashing my commits? I don't want to make a mess of my git commits.
Something like what is described here?
https://github.com/todotxt/todo.txt-android/wiki/Squash-All-Commits-Related-to-a-Single-Issue-into-a-Single-Commit

there's different ways to do this. this is just one:

0. if you want to make sure you can go back to the separate commits, make a git tag (tags are by default local to your private repo, you should not push tags like this to a public repo)
1. git rebase -i, and select all the commits to merge with the first one, update the commit message as appropriate
2. git push -f to update your PR

Also, please squash your PR down to one commit when you're done.

It is done. Is there anything i am missing?

Hmm, ordering of wagons seems odd with this PR.

What do you mean? Since most don't have power they should get ordered by ID. Oh, i see. Yeah without the PR it defaults to sort by running cost. I'll check how to make it behave like before for wagons.
Although i am not sure. There is already a running cost sorting. What should i do?

Ideally make it behave as it already does, just with correct power/running cost sorting first? You can easily fix the current power/running cost sorting by multiplying running cost by 1000 or so. No other changes, nor floats, needed...

This should work too. I checked quickly and sorting looks like previous. Let me know if it's not sufficient.

Hi. It's been a while since i checked this. Is there anything missing for this to get approved? I recall fixing every detail.
