BTW, no wonder Atom's huge. It apparently comes with a whole web-browser, not the "send-recieve packets and be done with it" type either.
Meanwhile I found answers to both of my questions, postponing the post could have saved me from tux..
1. found a search-replace plugin with the scripts plugin, more useful than default, attached ctrl+f shortcut to it.
2. portablefreeware.com has directions to stop those reg-writes. (I don't know why I didn't look there first. It's one of my goto places for portable apps.)
Some plugins seem to use the registry anyways. I'll probably make a portable wrapper with PApps or something.
