If your customer has a contract with Talkwalker (or any other social media listening tool), it would be a great option to be able to add the results from a specific topic to Oktopost (either as a stream or for content curation).
I know you're recommending Talkwalker and the tool has an API that other social media management tools integrate with for this use case.

Can you start the process of building an integration to our event marketing automation process Splash That?

Integration with video platform like Vidyard, so we can post and track videos easily from both platforms.

WeChat is our most used B2B social platform in China - it would be hugely helpful to incorporate it into Oktopost.

Feed content posted direct to social media platforms back into Oktopost.

You can now include gifs in your tweets, is it possible to integrate giphy and any other gifs sites to add a little spice to our messages

Currently Oktopost has a great calendar, it currently has a basic integration with Act|On however it would be great to enhance this by pulling/pushing Calendar items so that we can see all comms/content in one calendar rather than having channel specific versions.

Integrate with Sitecore and Snip.ly

Integration of XING - https://www.xing.com

Integration to Klout so you can see your Klout score and that of others you follow (like you can in Hootsuite).

The capability to subscribe to calendar from another such as Google calendar - I've just started using the sunrise app and this integrates with Google, asana and trello. Would be fab if the Oktopost could integrate too so I can see all my content at a glance.

I think I speak for the majority of digital marketers in that their website most probably has some form of social sharing buttons allowing their visitors to easily share content. The problem is, and whilst Oktopost is a great tool, that social interaction is lost unless it can integrate to a platform like AddThis as we are using two disparate systems. If Oktopost could integrate to AddThis it would allow all the organic social interactions to appear in the Oktopost dashboard providing closed-loop reporting.

It might be interesting to integrate with LinkedIn Publisher.

On multiple-user accounts, allow everyone to have their own feedly.

Slideshare provides a form to capture leads. It's great to know which ones cames from a campaign.

Ability to pull in Feedly boards in addition to categories/streams. This would allow for a narrowed down selection of articles to be pre-saved beforehand and then can be easily posted through Oktopost
