Extensions not showing in SKP Pro 2018

I have recently installed Sketchup Pro 2018 commercial license, and I’ve been trying to install my regular plugins/extensions through Extensions Warehouse, such as CleanUp, Material Replacer, Selection Toys, Pipes from lines, Path Copy… etc. standard ones, nothing complicated. However, they do not show up in sketchup even though they’re there installed and enabled in the extensions manager. I used to access them from tools or window - extensions, regardless of the exact location, it seems like all my extensions are blocked, i think i must not understand something very basic. Any help would be appreciated. Thank you

you also must install the TT_Lib in order to get the extensions of ThomThom to work.
