Hello,
Our theme includes a number of plugins but only 4 of them are required + WooCommerce if you want to sell the products https://www.8theme.com/documentation/xstore/plugins/included-plugins/
All the other plugins are just additional plugins that you may disable if you don’t plan to use their functionality. That’s why during the setup wizard you have a choice to install additional plugins or not http://prntscr.com/p13qsx
Also, today we plan to release a new theme update that speeds up theme a lot.
Your message is not very clear. What exactly is not comfortable and what guest services could not be used?
Regards
