Toggling certain features once a file is bigger than certain size

[kgoo124]

Describe the new feature being added
Once the file exceeds a determined size, a modal will pop up letting the user know that certain features will be disabled.

How will this feature improve this extension
String operations are very computationally expensive and they can only be optimized so much. At a certain size, some of our functions just aren't possible.

The size at which this gets toggled and the features that get turned off are still up for discussion.
