...or 100 million of them. I'm not going to gripe about how pricey things are getting in-game. Norrath has been good to me over the years but I still take a deep breath whenever I click the buy button on the Broker and watch all those zillions of plat disappear.
A fertile in-game economy brings with it certain challenges, and I'm reminded of Scrooge McDuck's vault and his wheelbarrows overflowing with coins. Surely there are more efficient ways of handling all that dough.
Recently Avenn pointed out in Discord the lack of large-plat controls in the ProfitUI CE pricing popup. It seems like only yesterday one million was a reasonable amount to stack up for large prices. But not any more. Since last summer Darq Side members have had a 10-million plat multiplier, but judging from the upper end of the Broker window lately, even that's anemic for certain popular goods.
So we have some small but useful improvements. Premium DarqUI and ProfitUI CE have a couple of new controls -- Darq Side members can still add and subtract prices in 10-million plat increments, and can also add plat to prices in increments of 100 million. The ProfitUI CE pricing window has been re-shuffled just a bit, adding 10- and 100-million buttons to the left-hand side, leaving the customizable presets over on the right.

ProfitUI CE

Adding 100 million plat to a price is a pretty intensive operation to say the least. In either UI, be patient when dialing up your astronomical Broker prices. It takes about 7 seconds on my mediocre test machine to add 100 million using DarqUI, and somewhat less time in ProfitUI since those price controls don't have a subtraction function to worry about.
