Is there 1) a better way of looking at diffs for bounties? And 2) a workflow for preventing person A from nulling the cells of person B

Okay so I got a lot of people climbing deep up my butt about merging a certain PR. Here it was:

https://www.dolthub.com/repositories/onefact/paylesshealth/pulls/34/compare?refName=main

It was homepage URLs from a bunch of hospitals. I thought, based on the PR, that the result would be to add a lot of URLs.

Sidenote: it overwrote a lot of URLs (trivially) which was an issue. But since the ones that were materially changed were big improvements, I elected to keep the whole thing. That was a judgment call.

More importantly: it also NULLed a bunch of other stuff, and that's what I didn't catch. I couldn't see it on the web UI.

do

`dolt diff qurdnbdb80mh9r8h5luf2colvgb9qusv f1he3sr553s52uredq318o4c1sb5u7uk`

to see that it set a lot of chargemaster URLs to NULL. For completeness, here's the summary:

```
dolt diff --summary qurdnbdb80mh9r8h5luf2colvgb9qusv f1he3sr553s52uredq318o4c1sb5u7uk

diff --dolt a/hospitals b/hospitals
--- a/hospitals @ 34furr8cg6kmqssri651pqvj69badgtg
+++ b/hospitals @ vvarbcbm1hkce793803v1ag0i9qgoieb

```

**Why this is important:** I want to be able to see what's going to happen when I merge a PR

**The problem:** The CLI diff is hard to read and the DoltHub UI doesn't show all the relevant changes.

_an example of the diff_

_an example showing how cells look when they're nulled_

**The solution:** I don't really know.

1. One idea is to have a button which does a test merge, and then shows me the diff on another screen in the web UI. Without knowing how things work on the backend I don't know if this is a big ask or a small one.
2. Write my own diffing tools to make better sense of the diff table. Maybe open it in a database editor or something.
3. Your suggestion?

Let me know your thoughts.
