When developing a new feature in a brownfield app that hasn't been subject to consistent autoformatter treatment, turn off your autoformatter.
Autoformatting is great. I advocate for it. But it can be distracting when trying to read through your new work. The hard-won changes you make get lost in the mix of automated changes. Once you've got the feature working, turn on the autoformatter and get that automatic quality.
This is a pretty niche piece of advice, but it helped me today.
