Preview/undoing of web editor changes

[Phoenix616]

When running the /lp applyedits command it will instantly apply the changes. It would be nice to have a way to preview which changes where made so that you can catch errors (That can happen faster with a GUI than with commands). Another solution could be to have a quick way of undoing these applied edits.

This is definitely possible to add, however, I'm not sure how it should be done.

It could be done via:

1. A separate command - something like /lp previewedits ..., however, most people just copy/paste the command anyway.
2. An extra confirmation in-game - so, show the change diff, then provide a message the user has to click to "confirm" - however, this adds an extra step, which could get annoying for people who don't want to check.

I'm not massively keen on either of those.

Would perhaps being able to see a diff view in the editor work as an alternative?

Hm, I see what you mean. Maybe a quick way to undo the changes could help? And a preview in the editor would probably also help. (maybe when the save button is clicked?)

I've thought about undo's before (more generally for all commands), but ultimately decided against it - it ends up getting kinda complicated and messy to handle.

I think the best place for a diff preview is in the editor itself. If you have the option to preview changes, it should remove the need for an undo command in-game.

perhaps another option would be to apply the changes as we do currently, but relaunch the editor showing which rows were updated and how (add/remove/modify). A bonus feature would be an undo or revert to previous setting?

I tend to use copy paste a lot after doing a /lp user xxxx editor and then run all the changes on the console. I've spotted a couple typos after re-opening the editor and had to manually update them (once I found them of course). :-)

I've moved this issue to the Web Editor repo.

I like the suggestion, hopefully I'll get a chance to work on it soon.
