//# Script version
const ScriptVersion = '2.3'

//# Settings
//- How long to wait for chat window pages to load when scrolling to the beginning of a chat (in ms).
//- Increase this if your connection is slow, and/or if you find that the script stops scrolling
//- prematurely. Very low values are unadvised, as you will be rate-limited by the server upon making
//- long operations, such as grabbing all chats in a community, or all chats in all communities.
//- Default value is 1500 (1.5 seconds)
const LoadDelay = 1500
//- Whether the script will save images as URIs directly into the file by default. Depending on how
//- many chats and how many sticker and image messages will be collected, it may incur a significant
//- filesize increase. Also, each compiled JSON will have its own setting for this.
//- Default is true.
