Your feature request related to the problem

Currently the clear data button wipes everything. There is no way to specify a subset of data to clear.

Describe the solution you'd like or alternatives you've considered

A set of checkboxes in a popup so that the user can specify what to clear.

Additional information

My current workflow is:

• Create a new OTP in Aegis
• Export Aegis codes
• Clear data in Authme
• Import Aegis codes in Authme

This would speed up the workflow by allowing me to only clear the codes while keeping all other settings.

There's a button in developer mode that clears only the codes, this should be a great addition
