I am new to confluence and its apps, i have recently installed Question for Confluences app and it shows up as "Questions" on the header, i would like to the text "Questions" to something else, please let know if that is possible.
Hi Sharat, Welcome!
I'm new to this community and have been using Confluence for under a year.
My suggestion to you is to go along with the standard names for things for a while, and keep a list of desired changes you might like.
Using an out-of-the-box setup makes your experience more comparable to others and fits in with existing documentation. You don't need to convert things like "Questions" into "Ideas" or "HowTo articles" into a "FAQ", when looking at documentation.
Furthermore, you may discover that Confluence features are pretty well thought-out. As a perfectionist, I'm tempted to "improve" and "adjust" everything I use, and sometimes that detracts from seeing and enjoying the good that is there.
Later, of course, it does make sense to customize as needed.
