You might be require to test your application url time and again, now typing it every time or searching it time and again might lead to time loss and may result in incorrect urls as well. Here the best practice it to bookmark the application url in the bookmark toolbar and use it.
There are lot of common tasks like stopping the server, redeploying etc. instead of running the commands you can write all of these in a script and keep that script handy to run.
The database url, port, credentials and other important stuff, which are generally required at the time of setup, but if not kept safely, will eat up a lot of time when required again. so keep them safe as well.
