So I am working on this little chrome extension that tracks the amount of time the user spends on certain websites and helps them reduce the time they waste online. On Installation the ext. asks user to enter max. of 5 websites which they find themselves wasting/spending most of their times on. Once submitted the list of websites is saved in the storage. Now the next part is editing the list of submitted sites.
Initially I made editing the list of websites super simple just on click of a button. Then after using the ext. for a while I figured this method makes it way too easier to "cheat".
My second option is to make the list of websites completely immutable. Once submitted it cannot be changed. The tradeoff here is that the user might want to add a website and then find themselves reinstalling the extension. Which has the potential of annoying the heck out of them.
Thirdly I am considering limiting the number of edits the user can make to the list of websites to something like 3.
Which one to consider or none at all ? Any other alternatives you can suggest?
