I would like to be able to see whitespace during a code review in Crucible similar to Visual Studio's Ctrl-R, CTRL-W. Is there a way to turn it on?
Yeah, that's not what I want. People are sloppy sometimes and mix tabs and spaces. That's easy to spot when I'm reviewing changesets in TortoiseHg for example (or a decent diff viewer), but not possible in Crucible.
Is that a feature that could be requested?
By the way, what is the definition of "insiginificant whitespace"?
I think this is the feature request you are looking for https://jira.atlassian.com/browse/CRUC-189
Feel free to watch it and vote for it, for now it doesn't seem to be a highly demanded feature, only one vote so far.
Regarding the meaning of insignificant whitespace it basically ignores amount of whitespaces if it is selected.
Hope that helps,
