Long time start8 user here since win8 beta, love the work you guys do. I just bought start10 without hesitation once I saw it. I have a few suggestions though, but I understand it's still a beta

1. default modern style theme should probably be solid black to match taskbar (can configure this in settings though)

2. with modern style, the translucancy shouldn't be blurry, matching the taskbar would be nice (though I guess the default start menu does that too, wtf? maybe give us some translucancy/blur configuration options?)

3. clicking user picture/name should do something, maybe open user folder and right clicking it can bring up a menu for user settings and other stuff? seems to be some wasted space up there, could put some settings related icons to the right hand side or print the windows version there.

4. always wanted this in start8, maybe this can be done in start10?: customizeable separators on the right hand side shortcuts (in win7 and modern modes)

5. some more options for "windows 10 style" like being able to remove tile backgrounds, and pin apps/shortcuts to the left side. maybe also the ability to add a real control panel link and "my computer" (This PC) too.

6. hovering over the start button should change color of the icon, also the transparency on it seems a bit wonky and broken after you click it. also, matching your highlight color would be a bonus too (if it doesn't already, I haven't checked).
