I really want what Atom is trying to achieve, which is essentially an open source Sublime Text, but I can't help but worry they're shooting themselves in the foot with their architecture.
It does use more memory, but that hasn't been an issue for me, either. The 4GB of Ram in my Macbook Air seem to be able to handle running Atom and anything else I need at the same time.
I tried the same in atom and it felt like my $3000 workstation was a netbook.
All the comments here keep saying that Atom is slow. For my use case it's not, and I'd like there to be some recognition on here that there's a very large subset of users for whom Atom will not be slow at all.
If Atom doesn't work for you, then it's cool for you to not use it. Seems like your circumstances are pretty extreme though. Most users will be fine.
Additionally, I'd be interested in seeing how Atom affects battery life. That's probably a pressing concern for many users even if speed isn't.
One wants an editor that can handle all common use cases though, not some kiddie editor that's only good for smaller setups...

I don't want to single out Kate. There are a gajilion text editors, and for most people most of the time most editors are fine, even though a lot of those editors have other equally weird ahem features.
I don't see anything bafflingly difficult about how Kate handles it. In fact it's similar to how most editors handle it.
Either use search/replace with regex (like Vim would do it), or or use the Control+J shortcut ("join") if that's just what you need (there's a similar command option in Vim too).
