Dear LeetCoders,

I always try to improve the learning efficiency while I am solving LeetCode problems.
One missing feature is an optional timer to track how long it took to solve a problem, as well as a full history of solved problems. This last would allow to identify the problems which I took too long to solve and work again on them.
I created a new external project called LeetPlug which covers these features.
I hope some of you will enjoy it, it is based on a Chrome Extension plus a web interface where you can play with your history anonimously.
Obviously it's totally open source, so you can check the code and use as you like.
The goal would be that a lot of people will join it, so we could compare our performace on the same problem with other users, "spy" what exactly people solved before successfully pass an interview and a lot more. This is an example of what you can get as result:

The entire project is a little outside my real background, so forgive me for any bug/security issue/ingenual implementation. Any comment/suggestion/collaboration is welcome on the main repository https://github.com/LorenzoBe/LeetPlug.

Thanks to all and I hope you will find it funny and interesting! :D

PS. After the development of my extension, I found there are already other timers for LeetCode on the Chrome Web Store. I discover these facts always too late :) but I think my implementation has some nice feature never covered by anybody!
