Client + window picker UX improvement requests

[dbish]

1. it's not clear initially whey you're juggling 3 windows when recording (web page, client app, window picker)
2. would have liked the UX for window picker and client app to be clearer they are separate from the website when launched
3. the icons are too big and are blocking my view of the screenshot for many apps
4. lots of apps make it hard to find (potential request: search for an app or window)
5. too many placeholder augmend icons, doesn't add value
6. some of the client augmend windows show up as recordable themselves, these should be filtered out
7. didn't realize i could just start without picking a window (that the window picker step was optional)
