not working at all

Totally useless.
You can use it for simple things that do not require any additional tool than the one already provided by wordpress itself.
If you want to do something nicer than normal, eg create pages or posts with TABS, here you see how big is the failure: contents into tabs are put randomly, no way to center images (yes you set it up but is not working at all), no way to change the colors of the fonts (yes you set it up but is not working at all) or the links; if you put the tabs in horizontal or vertical, no way, on mobile rendering all tabs are always at the bottom apart the first one = your readers need to scroll the entire post to see the other tabs = totally useless for tabbing…
Installed, used for days to make it working, creating and recreating posts and pages from zero, no way. TOTALLY USELESS.
