@tassoevan Tasso, thank you so much for this update, it took a while for me to notice the menu option added "Show on unread messages" :-) It actually solves many of the issues reported by users that people overlooked new messages in the past when they were not sitting in front of their computers. I was hoping for this fix for a long time - so from me a big thank you!
Maybe some further improvement suggestions for the case when the user has checked this menu item:
1. It would be nice to make the Rocket Chat client also blink in the task bar when it is started and there are still unread messages pending (e.g. when the user restarts his computer or closes and reopens the RocketChat client).
2. It would be nice to make the client also blink when it is minimized but there are still unread messages pending.
3. Think about making the "Show on unread messages" menu item checked by default, or maybe a silent installer option? Thank you once again!

@Anguel There are new features for tray icon/dock/task bar notifications being developed and tested, including the (1) and (2) that you suggested; I just need to test them more in all the platforms. About (3), I'm more into the silent installer option because "Show on unread messages" looks too much intrusive for the most common user.

@tassoevan Thank you for your reply. After some more testing I noticed that on some PCs the new feature did not work at first. But after some playing around or maybe it was the PC restart, it suddenly started working. Very strange, I will observe it...
BTW, it looks like if there is no other app window in focus the RocketChat window opens but when there is another app window in focus it only blinks in the taskbar - that's really nice if you did it on purpose ;-)
