If you ever want to experiment and check what another Wizard or pack from the same Wizard looks like, you can install SPMC or of course our own version based on that, DBMC.
1) You need to keep an eye on your storage space usage. Consider wiping DBMC/SPMC's data after an experiment, unless you have a lot of space to spare.
2) You can safely install different wizards/packs in DBMC/SPMC without altering Kodi's installation as they have different folders for their own set of data (hence why installing and running Wizards in both Kodi and DB/SPMC will double the space taken up)
3) If you really like a new Wizard/pack, you CAN try a dirty install over your current add-ons. If you find any problems occur, you'll need to wipe the app's data, then re-run whichever Wizard and pack will return you to the closest state your install currently has. Please note if support queries arise after a dirty install, the first part of DroidBOX's trouble shooting step would be clearing data.
4) If you have a T8-S or T8-S Plus, you can experiment in openELEC instead, however direct comparisons won't be 100% as different operating systems.
