improve discoverability of message search filters
I had been desiring the ability to use search filters in gajim for awhile when I stumbled upon some page that mentioned them and that there is a tooltip to inform the user about them. Even wanting them, I did not discover them within the UI. I suggest to make the tooltip more discoverable. Either extend the target area to the entire search box or add a question mark or info icon to the right of the search box that provides the tooltip.
