To ensure you select a pair of boxes of the same colour, the total number of boxes you need to select is 3 because with 3 boxes you get 3 grey boxes or 3 blue boxes or 2 grey boxes and 1 blue box or 1 grey box and 2 blue boxes. Either ways, you have atleast 2 boxes of same colour

With the help of the Search Filters option, users can now filter search results by type. They can do that by using the new tabs: Media, Links, Files and others. Searches can be done based on the particular time period like by typing in the date or even “Yesterday”. If users type in the name of a person, group, channel or bot, an extra filter will be applied to the searches.
