I've the Repository path pointing to an external drive.

If I run the App and the external drive is not available I lost ALL the TABS set sine last run.

A big waste of time, useless to add TABS again if I forget to connect the external drive before starting the App.

Steps to reproduce:

1) Repo path on external drive

2) The Drive is not connected

3) Open Sourcetree

4) All the TABS set (projects link) lost
