I run Calibre (Portable) from an external drive, where also my libraries are stored. What is the best solution to use the exact same settings on two computers?
I usually launch Calibre/calibre.exe, not calibre-portable.exe, and so far, my settings were not stored in the Calibe Portable folder but on the computer, which obviously isn't very portable

.
Solutions I'm considering / wondering whether they would work:
- running calibre-portable.exe instead of calibre.exe (is it possible to conveniently handle multiple libraries that way? I have two (none of them is in the 'Calibre Library' folder) and would like Calibre to remember which library I opened the last time.
- storing the configuration data on the computer and syncing them to Dropbox (with Dropbox Folder Sync)
- moving Calibre configuration directory (is it possible?) to either Dropbox or the external drive.
Funnily enough, two years ago I struggled with a similar problem

Back then, I was advised to "make a customized COPY and use calibreportable.bat which is found in the resources folder" - would it help in my present situation? And how to do that?
Thanks in advance!
