Well, I accidentally pressed something and this section disappeared, problem is though, I don’t really know what this section is called. What should I do to bring this section back? Sorry for being noobish, Just started using the software 2 days ago.
This is the section that disappeared. This tool is really useful for me, but I can’t find it coz I don’t know what it’s called.
The part of the UI which you can play animations. the one with the play button.
File / Load Factory Settings is the easiest way to get back to the default layout
You can also split a window (RMB on the window border or drag the corner triangle) then change a window to a timeline using the drop down list in the bottom left corner of the window
That did the trick~! Thanks buddy 
if you see on the far left the little icon there has a list of 17 options, also in the lower left corner and upper right corner there are 3 “/” running parallel and decreasing in with to form a triangular shape, if you click and drag one of those it will split the view or collapse a view depending on the direction pulled
