Thing like this is needed for people who quit game for a while and then came back.
Mega-stones quests are long and progress is easily forgetable, I for example, don't even know where should I go now as of houndoomite.
I've already checked 5 times by clicking them again and nothing happens. Barrier's up and "this crystal was already activated" on every single one of them.
Sorry, my bad. I mean 3rd floor of the Dragonspiral Tower, yes. I haven't completed the quest, it's the first time I'm in the tower. Can't make the electrical barrier go away.
To add either on Discord or In-game.
It'd show the progress of your quests. For example you started Legendary Birds quest and you took a break from the game. Instead of going back to Shamouti Island you could just check the progress in your logs.
Same goes for other quests x/x trick room, x/x pvp battles etc.
