* waybar-hyprland also exists on FreeBSD, so drop -git suffix
* Added wikipedia links to regex topic.
So that people who don't know much about regex/programming in general can read the regex topic from wikipedia in details.
* Edited no_direct_scanout description
It is very important because many people are having graphical issues with their game and setting no_direct_scanout to true works. See this discord link (https://discord.com/channels/961691461554950145/961694014615208048/1091353694974517349) from the hyprland discord server. See this video - https://0x0.st/HHLn.mp4
* Added the regex cheatsheet link.
Added the regex cheatsheet link to the swallow_regex description box. Users should need to know what are the different types of regexes and how to use them so that they can swallow whatever window they want.
The path to execute the kde polkit agent has changed as of version 5.27.3, and now resides in /usr/lib64/libexec/polkit-kde-authentication-agent-1 instead. Because of this, the "must-have" page should have its instructions changed to reflect the update.
* Update mouse cursor documentation
I was having trouble with getting the cursor to work on chromium/electron flatpak applications. I updated this section of the documentation with what worked for me.
* Update _index.md
* Move archwiki link to the bottom of cursor no worky
...so that the cursor can worky. ;33 also update flatpak part.
I've noticed the listeners do not update while their values are only present in the class attribute, so either the scripts would have to be merged to one output or one can use a hidden element like this to keep the variables updated.
