Google's note-taking and storing service is growing up slowly, but nicely. Today Google Keep is receiving a new update, one that's all about the ability to easily start notes that contain a link to a website.
If you're on a computer, you can use the new Google Keep Chrome extension. This lets you start a note in Keep from any website, and the address of the page you're on is saved in the note automatically.
On Android, Keep can now receive links from other apps to accomplish basically the same thing. So when you find something you want in a note, just choose Share (no matter what app you might be in), and choose Keep to create it. In both cases (regardless of whether you use the Chrome extension or the Android app), the new note should have the title field autocompleted with the title of the website you shared, while the exact URL will be in the contents of the note.
Finally, today's update adds support for hashtags. You can use these to label things, but unlike Keep's other, pre-existing labeling system, hashtags can actually be added to the contents of a note. So no more hitting the Labels button and applying something from there, you just write the hashtag inside the note and the labeling is complete.
