Please find my feedbacks after using DNN 7 for the first time. These may be bugs or ideas about some new features. Hope this will be of interest to you.

• The definition of the skinobject meta has disappeared but the code is still there. To define a viewport if we create an html responsive skin, it may be usefull to keep the definition.
• I know it’s a .0 version but it seems there is no additional language packs like in the 6.x version. Please confirm.
• I had a problem with the dll Newtonsoft.Json used by the new host menu. When I installed DNNArticles which I already used before, it replaced the dll with an older one making it impossible to use the menu again to add modules on pages. Is there a way to protect the dll ? (I thought assembly version was managed by the specific sql table but it seems the dll can be easily replaced).
• I like the new host panel, it’s very convenient. Yet it’s not easy to scroll to the right when I need to add a module, especially when in Edit mode where the panels are displayed with borders.
• For the module admin, the return of actions buttons instead of the manage panel is interesting. Is there a way to still use the manage button (v6 like)? During my tests, the action buttons were not always correctly positionned and I had to hover the Edit Page button to have them get back to the right position. Have you too noticed this weird behavior? 
• When I am in Edit Mode (Edit Page now), everything is disabled except the module I hover (it’s a nice way to isolate the content). But if I need to scroll (to the right for example), the focused is lost. When I tried to click a link in the module, it scrolled me back to the left and I couldn’t do anything. Is there a way to correct this or go round the disabled effect?
• My last point is about the minifier. The host settings are well saved but not applied (ie: Content Version or minify css). I had to edit the web.config to increment the version or activate the css minification.

I agree with you. With all these changes and potentials feedbacks, a dnn7 forum is a good idea.
