Customize sidebar - add links

I would love to be able to add custom links in the sidebar. I have a form that I need to fill every day or a web app I check every day. Of course I can add it as a task but I would check it several times during the day, having the link in the sidebar would be so convenient.

I also tried to add it in the Quick notes, but the notes don't have hyperlink feature or rich text.

In general, I would love to have something that would act like a parking spot for links that need to be checked irregularly.

Like a section below Tags section for these custom links. (Just link and title for each of them with the possibility to open any of them in the web)
