just a few thoughts to help streamline things:
make it so you can start a new quest from the quest rewards page, seems like a needless waste of page loading to go back to the main page to start the next quest.
same goes for the battle quests. it understands a quest is going on when it gives you the exp when you win, why cant it also give you the item reward and have a button to start the next quest?
can item hunt and blue building quests be updated to have the "search shop" button the more modern quests have?
on an unrelated note a submit button at the top of the quickstock shop pages would also be handy so after i hit the toggle all button i can just hit subit without scrolling to the bottom (yes. i am that lazy...)

more pageviews = more random events.
that's not a bad thing when it's not abused.
i love myself some sbq invites and some amulets with that one extra page load
shrug its added server strain and the site goes down often enough. that and i have to pay for data, pages add up.
that and battle quests take way too much clicking...

If server strain is an issue, there are a lot of other things that should be removed. (VENDING)
Server strain is nowhere as much of an issue as it was a few years ago
vending is also a lot less of an issue than a few years ago shrug i just came back from having stopped playing 3 years ago... kinda miffed i cant use my mcab anymore...

No. During events where we have to "catch" floating items, I love those damn extra pages. I get 90% of my event item REs while questing.
Although I go agree about the battle quest one. That is kinda excessive to get prizes and xp on two separate pages.
Honestly, I get more floating items from opening new tabs for the items than I get from the "Finish Quest. Start New Quest" two pages. Just saying. ;)
Though I wouldn't mind having a shop search for IH and BB. Though currently for BB, you can at least hover on the items and use the new shop search links, which is way nicer than a few months ago when you have to open tabs and c&p all the names. I would AT LEAST like the ability to hover on items for IH. Also BB is getting an overhaul soon anyway, so I'm not too worried about that.
[edit] My own addition: Add BB and IH to the goddamn quest widget. That is all
I would fully support the addition of the "Shop Search" button to the Blue Building and Item Hunt quests!
I don't mind the extra page views because they increase my chances of getting stuff!
Personally, I would very much like to be able to start new quests from the quest reward page, and cut down the clicking required for Battle Quests. If I want to have extra page views, there are lots of more productive ways to get them. I'd rather add a few more activities than take extra time on questing. Also, there are times when the extra mouse clicking is hard on my wrist, and I'd rather skip it.
