I've been finding tooling more and more important lately. When you make something easy and convenient, your whole life gets easier and more convenient.
For example, terminal windows are infinitely useful, and being able to quickly execute some commands in the context that you want is invaluable. But opening up a new terminal window and navigating to the correct location is hard. It takes time, and you have to pay very specific attention. And I know, there are different shortcuts that attempt to make it somewhat easier, but none of them work. It's all just expensive. As such, I got used to keeping about 47 different terminal windows open, in all the locations that I typically use, because navigating to an existing window, even if it is one of many, is much easier than opening a new one.
Well, not anymore. I wrote a plugin for my IDE (because a good one does not seem to exist) which opens a new terminal window in the current project (the use case for about 99.9% of my terminal usage). It's simple, it's convenient, and it's already there where I am. This makes opening a new terminal window trivial, making them pretty much disposable. This has drastically changed my workflow over a very small period of time. Now, I have no problem quickly popping a terminal window open, executing a few commands, and just closing it. Because opening a new one is practically free.
This kind of workflow is why tooling is so important. We should all pay a little bit more attention to it.
