Completed the first phase of my “Customized Tweet Feed Display” Twitter app. What it does is: first, allow you to define 1-3 customized “tweet feed groups” (such as, for example “Social Media News,” “Travel Alerts,” etc) Then, you specify the Twitter username(s) for each custom tweet feed group, along with the number of tweets to see from each respective Twitter user. Following that, a combined group of tweets is displayed for you, clustered within each individual “tweet group”.
