Nice app, but taking too much time to load

On my machine, when I open the apps, every app loads fast except Slack showing "Connect to Slack" for long time. It was good in the previous versions, not sure why it is happening on the latest version. Thanks

Pinned message regarding

recently pinned message should be shown above all the messages, like in twitter. at least for channels or groups. there are many people and messages. so most of them misses this pinned messages. of course they can see by click on pin icon, but they don't.

The App heats up my MacBook Air

When I run the app on my machine it starts to heat up. The heat increases to a great extent (I can literally hear the fan running at high speed) when I use the calling feature in slack.
