What is your suggestion?: Adding the plugin "Dark Mode" to Alora's Runelite client.
Is this in OSRS?: Yes (if you use Runelite for osrs)
Has this suggestion been accepted already?: Not to my knowledge no.
How would this benefit Alora?: I am a big fan of the plugin personally, I feel it would not only make the game unique as I have not seen it before but it's something nice and different and as I said it does look really cool.
