In previous versions, incoming IMs that have not been read caused the tab for that IM to flash until the respective chat was selected. That was helpful when several IMs came in at once to remind that there are unanswered calls. In 1.19.0 there is a short flashing only when the IM comes in, but it stops almost immediately. Say you are afk and group-IMs come in. You return to your pC and now have to go through all open IM-tabs to check whether anything came in during your absence. Previously that was easy to see. This is especially helpful when you provide customer-support and often have several customers contacting you at once. Now that the reminder-flash is gone you have to constantly scan open chats "by hand" to make sure you are not missing something or ignoring a customer. While we're at that: a weak point of previous versions has always been that there is no notification of IM-windows opened past the width of the Communicate window, resulting in IMs not being noticed until another IM-window is closed. There needs to be an indicator (or better: Browse Unread IMs Control) on the communicate window.
