Hello, I'm author of CatChan, which is a script which can generate cross board/domain catalog with tag filter. Do you operator or administrators want uboachan to be supported by this script?
You can download it from here. It works in lainchan, 4chan, 8chan or KC.https://raw.github.com/Dogman8/CatChan/develop/CatChan.user.js
Cross board/domain catalog with tag.
Other basic features, such as favicon or notifications.
Also refer these:https://lainchan.org/%CE%BB/res/10247.htmlhttps://8ch.net/operate/res/38974.htmlhttp://8ch.pl/meta/res/13.html
You can ignore my proposal. Stating stance of power users may invoke conflicts sometimes.
