I answer to myself... If anyone run into troubles loading Hooh mods: you need the [Hooh][REQUIRED FOR ALL ITEM MODS] category_reserve.zipmod mod !I tried, to be certain, but unhappily it doesnt' work either... Some mods I put in the MyMods folder are showing in StudioNeo with no trouble.
Eg., after dowloading this small mod from Hooh ("Niche mod") : Mega , I tried putting it in the Mymods folder, the mods folder and even in the SideLoader folder, checking each time if it is correctly activated by KK, with no luck in the end
Btw, using the "Install mod..." tool in KKManager failed too. A great mystery...
I found it with a lot of luck, by looking for something else. And you can download it here :

It seems that the game do not create the needed items categories by default: this micro-mod creates it, as far as I understand...
