Hi, I have some questions:1) When i upload a cover for a spaces (but also for orgs and user too) on mobile phone it will be zoomed in. How can I auto adapt size of cover for mobile phone?2) Can be a module in homepage blocked when i scroll the timeline? I'd like (in a 2 column layout) scroll on the right (timeline, feed, posts or) while on the right user will see always same block. (as happen on facebook for example)3) I can't add reaction. I was in Forms->Data Lists->Reactions but "add items" button is blocked, and if I edit a reaction, i was't able to change image (just text)4) I removed everywhere all button related to "friendship". Users are able just to "follow", so there isn't "Friend concept" on community, but if I enable "privacy visibility" for posts,orgs etc they can select "friend". How can i remove anything from privacy visibility (keep just "only me", "public" "followers")?5) At the moment users can chose a Full name during the registration. Is there a plugin/option to ask for a Full name (it will be the Displayed Name, and could be same for more user) and "Nickname" (unique value) that will be below the displayed name on profile? (as twitter, to be clear)6) Is there possibility to log in with nickname? (if there is possibility to do it in previous question)7) How can i change circle color (and on-hover) of timeline items (like, comment etc)?I'm sorry for too much questions all togheter, and thank you very much for replies!
