Thanks for the interesting plugin, rich features even in the free version! But there are a number of flaws.
1. Sticking mode does not work on mobile devices.
2. On the computer, the sticking mode also has defects. To see this, you need to do the following actions (use the menu option with the logo on the left and the site that has a width less than the width of the browser window, for example, 1100 pixels for site when the browser is 1920):
a) scroll the page down until a sticky menu appears: b) reduce the width of the browser window so that the menu items go to a colapsed state; c) click on the colapsed menu item button to see the menu items; d) return the browser window to its previous maximum width.
Before the update after these actions, the logo placed in the menu on the left remained on the field outside the site. After the last update, if you perform such actions, the site totally freezes and does not respond to scrolling (only clicking on links works).
PS.: Sorry for my English, but it seems I explained it clearly.
