When you copy and paste a chunk of text that includes tabs, they are usually replaced with spaces. The number of spaces matching the value of the “Tab Size” or “Indent Size” setting (both are the same for me). It does this despite “Use Tab Characters” being turned on under indent size.
Fixing that requires searching and replacing four spaces with the tab character.
It’s a relatively minor but annoying issue.
I think this is a known error, at least I’m pretty sure we reported it before, since it’s been in all 6.x versions. If so I just want to check if this is going to be fixed in this release. If not, then hopefully there is still time to fix it, or at least to get it on the list for the first post 7.0 patch.
The latest several betas of 7.x finally fixed the search and replace so that you could replace with tabs, so that helps. But it would be better not to have to do that.
