+* ibuffer
+
+ibuffer is an integrated buffer management suite. 
+
+If you have Emacs for a long time open or just like me, like to switch between different projects on a constant, keeping a good overview over you buffers is important.
+
+That's why I added the settings which I found [[https://olddeuteronomy.github.io/post/emacs-ibuffer-config/][here]].
+
+I adjusted the config accordingly to my modes which I use on a frequent.

+To spice things up, I enabled the same Nerd Icons which are visible in dired to ibuffer. 
+
+Not necessary but an eyecandy to look at!
