 # LibreOffice has improved a lot over the years. It also works

+# Note that we use `libreoffice-still` instead of

+#
+# Edit: Actually, maybe writing things with Vim is still the better
+# option. This makes whatever you write a lot more portable since
+# you use a human readable file format that someone has probably
+# written a library for in other languages. You also end up with
+# a whole lot better git support.
+#
+# LibreOffice Math is very difficult to use compared to simply
+# using LaTeX. The amount of clicking required for a basic
+# formula takes a lot of effort and the cryptic commands used
+# in its shell don't follow LaTeX at all.
+#
+# LibreOffice Base seems like an attempt to bring database
+# management to less-savvy users, but traditional command line
+# interaction with the database seems like the better option here.
+#
+# Draw and Impress seem like both are easier to future-proof and
+# accomplish with web technologies.

+# For me, it seems like I'll only use LibreOffice Writer and
