This article (17 pages) was written to accompany an Overleaf help item. It explores the meaning of underfull or overfull boxes and examines the calculation of badness using an \hbox with finite and infinite glues. We have tried to provide a range of examples to demonstrate various aspects of TeX engines’ box-construction behaviour and the underfull or overfull “diagnostic messages” issued by TeX engines during the box-creation process.

The changes package, distributed with TeX Live, allows the user to manually markup changes of text, such as additions, deletions, or replacements. Changed text is shown in a different colour; deleted text is crossed out. The package allows definition of additional authors and their associated colour. It also allows you to define a markup for authors or annotations. (Here's another customised example using avatars for the author annotations.)
This example demonstrates how to write polyphonic or instrumental music on Overleaf, using M-Tx (.mtx) syntax.
This was made possible with a custom latexmkrc file. The music piece examples here were taken from the M-Tx documentation.
