I love customizing my IDE. Especially when it comes to the visual appearance. I spend hours finding the right theme, customizing the keymaps, adjusting and arranging the windows so that everything looks exactly the way I want it to. The IDE is something very personal. Or at least it is for me and many others. There are also psychopaths who install the IDE and just leave everything as it is. Yes, exactly with the default color theme! That's really beyond my comprehension. But anyway, this is about something else. It's not about the IDE but about the person in front of it and what you do with it.

Its a Cult

Thinking of Neovim? You guessed right. I worked with it myself for a few months. And still do regularly but for all that is holy, it's not the only true IDE for “real” developers.

VsCode is not the best IDE (blabla its a Code eDiTor blabla) just because it is the most widely used and has 9123012390123 plugins.

NotePad++ is the best IDE.

No matter what you use, don't defend your IDE like it's your first born child and the most sacred thing you own. And above all, don't take it personally.

Productivity is not due to the IDE

A shocker! Spending 412 hours setting up and perfecting your IDE (Neovim) does not make you productive. Quite the opposite. Get to know your IDE, learn the shortcuts, learn what you can do with it. But above all, take care of THE CODE. You use the IDE for coding so use it for that and not to make it look like something out of a fucking Matrix Hacker movie.
And I know what I'm talking about, I've done it all to a certain extent. It's about the code in the IDE and not about what's around it. The feature won't be finished any faster, the bug won't disappear any faster.

Your Identity is not your IDE or vice versa

Like food, the IDE is very personal. And it's okay to take your time and find the right colors and icons. And it's even more okay to get to know your IDE properly. In fact, it should be a must. It's a tool and if you know how to use it efficiently - oh boy it's a blast.

But your IDE is not the best. Your IDE is not your favorite sports team that you defend to the death (which is just as stupid). Your IDE is special. For you. And that's perfectly okay and, up to a certain point, even healthy and right. Try yourself out. I've tried a lot of things and still do. I've tried everything from Neovim to Jetbrains. I think it's like programming languages. There's something for everyone.
