While I won't deny some of the points brought up here, ease of use, meetings, mobile first, I have to also admit spark still has some catching up to do with features I love with email

1) Just because you reduced your email traffic, doesn't mean you didn't create more "noise" aka rooms in spark that sometimes spiral out of control. I would love to see some type of folder structure to keep this manageable vs a long list of rooms after rooms after rooms

2) You mention threading in emails as not easy to catch up..I beg to differ. I feel it is super relevant in chat rooms. I have been in large spark rooms where there is so much overlapping conversations that you lose sight of where the question is and where the response is since 10 messages down is the response. It would be great to intertwine them. Even a simple mark message as unread would be useful like email to go back to a post later in the day. Sure pinning could solve it but I am still waiting on that feature..

3) Search is still very rudimentary. Yes I am looking at the new acquisition Cisco did to see how it pans out plus searching encrypted messages is a challenge but at the end of the day I need a super smart predictive search engine with easy to use filters to narrow down posts. I want when the search is done by a post author or date/time range to provide me a custom view in spark of those messages and not the way it is now

4) Feature parity isn't perfect across platforms either on Spark, on desktop windows, I can't see status on content being uploaded vs browser.. emoticons won't render on desktop correctly vs mobile.

5) Need seamless escalation from spark meeting to webex meeting..still some work to be done there.

and Yes i have submitted these through feedback.

I love spark, love the mobile platform, calling and compared to Jabber over lossy mediums, the performance rocks. We just need to tighten up the UI and add features quickly vs pointing to API and having partners close that gap for Cisco...IMHO
