I wrote a JSON script that, used along with the Redirector Chrome extension, automatically redirects journal webpages to your institution's proxy, (e.g., https://onlinelibrary.wiley.com/doi/10.3982/ECTA15510 → https://onlinelibrary-wiley-com.ezproxy.bu.edu/doi/10.3982/ECTA15510), so you can read and download the papers directly if you have institutional access.

My favorite offline LaTeX editor.

The package can automatically send proofs to the appendix, repeat in the appendix the theorem environments stated in the main text, section the appendix automatically based on the sectioning of the main text, and supports a separate bibliography for the appendix material.
