Integrate similar image previews as in Skype / Slack, rather than just "Download":
- Enable copy pasting of an image from preview
- Enable zoom on image when passing mouse over it
- Open preview in a sub-window for better viewing

Would be great to do an Asana plugin

A lot of AD forests have Profile Photos in them. Mattermost provides no administrative capability to set profile photos. Therefore, just yank them out of AD? Would prevent complex UI from being necessary and give us AD admins a more fancy way :)

As of now, mattermost custom integration plugin is available to all users on Team edition. It will be good if there is a restriction like "personal access token" can be enabled for particular users.

Looking for a Integration for video conferencing system "Lifesize"

It would be great to have a first class Mattermost (tm) integration with IFTTT so external integrations can trigger Mattermost API events.

Here's some examples of the things you can do with IFTTT integration: https://ifttt.com/slack

As we use GoToMeeting, the Mattermost plugin for Zoom does not help. We would verymuch appreciate a similar possibility to integrate GoToMeeting.

integrate with a business whatsAPP

It would be great to have an integration with the osTicket platform to be able to receive notifications of new tickets or ticket updates.

In addition, it would be even better to be able to send messages to the osTicket API to create new tickets.

It'd be great if in the integrations you could assign a bot account ownership of a webhook.

As described at https://forum.mattermost.org/t/auth0-single-sign-on/6728

As a mattermost administrator, I want to be able to configure authentication with Auth0 as an identity provider. Auth0 supports a variety of standards, so it might be best to implement it as OpenID Connect.

I would like to add a string to the header and purpose every time it is changed via a plugin, but this is currently not possible as there is no hook for channel metadata in the plugin API.

Instead of Amazon S3, being able to use MS OneDrive for media storage.

This would be great for companies who have this large amount of storage essentially 'free' with their Office 365 accounts rather than spending for S3 storage.

Keycloak is one of the most popular IDP providers used.

It would be great it Keycloak could be supported as simple as other authentication providers based on the same technology.

Add Mumble/Murmur voice integration.

Murmur is the server component of Mumble, and is lightweight, with highly configurable options and good encryption and voice quality. I think it could really be a powerful voice integration to consider, as it has an easier to use interface than say, Jitsi. Voice inside mattermost would make it a Discord killer imho.

Add integration for YouTrack by JetBrains

As of now, the integration between Mattermost and Dropbox relies on third party setup such as Zapier and Integromat:
* https://zapier.com/apps/dropbox/integrations/mattermost
* https://www.integromat.com/en/integrations/dropbox/mattermost

It will be great to have a built in plugin to perform this functionality. For example, send a notification to a channel / direct message when a file is uploaded.
