I have been recommended to use following plugins but after extracting them to plugin folder , when I tried to access plugins from the main menu, my box kept crashing, which worked fine after I deleted them.Can some one please have a look to see if they need any modification for vix?
What plugins are you actually trying to hide? Reason I ask is it might be easier to alter the code of the plugin to hide it if the plugin comes with it's .py code. Not saying it can be done but might be worth having a look.
Why do you want to hide and not delete ? I just deleted them.

I deleted them almost immediately and haven't noticed any problems. I'll see how it goes - easy enough to restore.They are related to kodi plugin & apparently you shouldn't delete them as it may effect kodi's performance
