So I'm familiar with the concept of add-ons/mods from playing WoW and ESO but for GW2, I can't seem to find anything that's been updated at all since 2015. I know with those two games, because of the constant updates that the add-ons need to be updated as well but don't know if the same logic applies to Guild Wars 2. Overall, mostly what I'm looking for is a World Event Timer that can be put somewhere on the UI so I can just take a glance of what's coming up and not have to use my phone or alt-tab to Dulfy's timer.
I'm also looking for something that is like Auctioneer or the Tamriel Trading Company addon as well but all the ones I'm finding with google searching are 2+ years since they've been updated.
Any help would be appreciated, especially pointing to a main hub site (like how ESO has esoui.com) that keeps versions of the addons updated would be great too.
