The following was changed in MO 1.0.9: "nexus id and installtime columns are now hidden by default". To change what tabs are shown go to the 'tabs' row at the top of the left pane, right click and enable nexus id (modid). An excellent article orginally created as a thread by GSDFan and now to be found in the advanced tab of the MO wiki, section 'managing categories' describes how to handle (custom) categories. An alternative is to select a mod, right click and select 'open in explorer'. The file meta.ini contains all the info about a mod. is it possible for ALL new mods to get inside my new category (new mods need testing) after installing?or I have to install them first then use 'right click -> add/remove categories -> [check] new mods need testing'? thanks
