This question is an exact duplicate of:
I login to my SO mobile android app to browse for questions/answers for very specific tags every time. I wish there was an easy way to do that in one click: like a favorite tags or a recent tags menu/button somewhere on the home screen or feeds page. Right now I have to either search for tags myself or open a similar question, click on the tag to go to tag filter view and then retype the filter. I wish this 2 or 3 step process is reduced to a one click menu/option on the home page/menu.
Thank you guys. Again, the app is wonderful.
