It seems this should be a basic and comomon requirement, but after an hour of searching instead of getting on with the task I want to use it for, I can't find an effective solution for formatting HTML in Notepad++.
I've visited Formatting code in Notepad++ and How To Auto-Format / Indent XML/HTML in Notepad++ but
XML tools plugin - no good because it doesn't even align opening and closing head tags.
TextFX HTML Tidy - no good. Missing dll, link from menu to dll broken and all SO solutions involve putting the dll once found into plugins/config directory which my install doesn't have (Maybe I could create it, but I want an easier solution now)
Tidy2 - won't install
I'm using Windows 10 on a 64-bit machine. I love Notepad++ but this sucks. Please put me out of my misery.
