All those additional icons in the ui?

Hello Pilou! Thanks for the reply. I do mean some other icons, not those that you refer in the link you put. There are some icons that have to do with viewport matters and some other utilities as it seems (I do see them in Chip Walters toutorials mainly, as in the video below). But, anyway, my question had to do with the way we install plugins to Moi, in general. I tried to install some plugins from the page of Max Smirnov (I extracted them to the 'commands' folder of Moi) but as far as I see, nothing new appears in the ui of Moi. Sure, something I do is wrong but what?

Thanks for any help...
