Since I switched to Linux, I’ve had to find a replacement for my beloved notepad++. I went with Atom because I like the project view in the sidebar and I’m too cheap to pay for Sublime.
Because I miss notepad++ so much, I’ve been slowly trying to make Atom behave as much like it as I can. One very simple plugin that helps me do that is selection-highlight, which highlights all occurrences of a word when you double-click it. For something so simple it’s really helpful, and something I missed a lot when I switched to Linux. Sometimes you just want to know whether the id you logged in a few different lines is actually the same, and it’s really nice to be able to do that with only two clicks.
If you use Atom, I recommend the selection-highlight plugin, and if you don’t use Atom, I recommend trying it out. It’s free and there are about a bajillion plugins :)
