Firstly, great work! this is definitely a worthy rival for Omnimo for rainmeter, im sure over time it will be awesome.
Below I've outlined some notes, you've provided me many hours worth of customization's.
-Separate "people" from "whats new"
-I only have a small space to scroll through "people", and i can only do it at the bottom of the screen. The top of the screen doesn't work.
-To present a facebook widget which acts in a similar way to the time app. Clicking on it will take you to the fullscreen "whats new" page
-Option to load at startup, that way I won't have to look at my desktop at all. (most people dont know how to set the option themselves)
-Ability to lock all tiles, I bump them quite often.
-"Win8Menu" functionality, flicking through programs from the left side. A Bar on the right side you can slide out with various shortcuts (pinned apps, websites and etc under a sub option) The bar on the right would have a start button
bringing up Mosaic.
Win8Menu may or may not be discontinued, there has been no response from the developer as yet.
-"Start" text item, logoff/userpic and shutdown/restart icons as presented in this pic: http://th06.deviantart.net/fs70/PRE/f/2011/167/0/2/another_windows_8_start_screen_by_fediafedia-d3j2ahq.png
I would expect them to be static items.
Really Awesome Idea's
-Built-in file explorer: One of the main reasons i downloaded this program is because I'm sick of the traditional windows control methods. I work full time on my pc and quite often have to go browsing through folders. Using libraries you
could make something really cool in mosaic. Willing to talk about how I can help!
Thank you for Mosaic!
