Rant - WP8 usability issues

I've been using WP since WP7 and now I totally enjoy my 920. However, over the last couple of years I've accumulated a lot of usability issues with the phone. These are either issues that either I've noticed or others (aka toddlers) have! 1. The stupid bing and back button - Why is it that every time anyone watches a video, they end up clicking on the 3 hardware button and just mess up things? Its high time MSFT provided options either to disable these buttons during video playback/games or provide a better option. 2. NOTIFICATION - I know.. live tiles does it all... but I know notification is coming, so no complaints there. 3. email alias - Outlook provides multiple email aliases. Why doesn't the native mail client in WP allow me to use a particular alias when sending mails? Its a total let down! 4. Skype integration - I don't have to say much about this, but it sucks!!! 5. Lack of icons in Settings options - Why did Microsoft decide that its easier to look for the text "email" or "ringtones+sounds" rather than look for a corresponding icon/picture? I guess they don't want illiterates to use WP!! Also, has anyone in Microsoft tied using WP8 on a language other than the ones they can read? I just tried switching my display language to polish from English and I had the most horrible phone experience ever! I cant imagine my misery if I had switched to a different script. :) ....
