How to safely remove an app

Hey there

One of my sites was recently causing an issue with the events app, and I wasn't using it so I removed it from the app.php file and that problem was fixed.

However, 'Events' still appears in the 'Apps' menu and of course, the tables still exist in the database. I have a scheduled task set for the twitter feed but it's not working, and when looking in the scheduled tasks list, it's reporting a status of failed in the events app. I have never set any scheduled tasks in the event app at all but it's obviously interfering with the task for Twitter. The php error log is reporting errors within the event app too so just removing it from the apps.php file isn't enough.

So, I want to remove all traces of the App completely from this instance of Perch. Is it just a case of removing the 3 events tables from the database?

Cheers.
