Reminder function

Hello, Your courses are really great. I love it. But one function would make it better :) Maybe that function exist and I just don't know how to use it. Then maybe you can help me? "Reminder function" I mean for example that situation: I'm now on course named "Swift 2.0 Functions", and suddenly in one of the steps you use "while" command. I passed the courses "Swift Basics" and "Swift 2.0 Collections And Control Flow" but actually I forgot what exactly "while" command is, and when to use it. So is there some option to quick find and remind everything about "while"?

For any help thanks in advance, and sorry for my English language, it's not my first language.

Hello Wojciech,

I don't think that exact function is available on Treehouse. Here are a few suggestions that might be suitable.

The closest feature we have for that I believe would be bookmarks. You can bookmark a course and quickly refer to the videos. Another option is the Workspaces feature. If you find yourself needing a refresh on syntax or a concept, create a few Workspaces that demonstrate that so you can quickly launch them and review the code and your comments.

You may also want to consider creating a folder in your browser bookmarks and bookmark a few course videos there for quick review.

I hope this helps.
