How do you manage URL lists you need to revisit?

I’m launching Multi URL Opener tomorrow and would love to learn how you handle recurring sets of links today. Do you keep them in bookmarks, a spreadsheet, a document, or somewhere else?

The extension lets you paste or import a list, remove duplicates, save named sessions, and choose how the links open in Chrome. I built it for tasks like SEO reviews, QA checks, and research.

What part of revisiting a URL list takes the most time for you? I’ll use your answers to decide what to improve next.
