Users can define custom processing and viewer commands for any file extension, such as setting up textopdf with pdflatex or xelatex, and choosing from various PDF viewers like Sioyek or Zathura, as detailed in the Configuring Routines section.

Supports forward and reverse jumps between LaTeX source and PDF output, with configurable commands for viewers like Sioyek that enable precise navigation, as shown in the Settings for SyncTeX section.

Allows piping buffer content to the processor to avoid constant file saving, reducing the risk of overwriting files, though it disables SyncTeX, as explained in the Using Buffer As Stdin section.

Compatible with many PDF viewers (e.g., Sioyek, llpp, MuPDF) and browsers (e.g., Falkon, QuteBrowser), with detailed configuration hints provided in the README for each.
