1) I guess a jackhammer and all those electrical tools shall help you. All those construction vehicles you can request once vehicles shall be planned & added in.
4) Saw people mentioned this so I guess we might get a flood light to be inserted into the game sooner or later.
5) I recommend that storage chests would behave like those in Minecraft by either refusing to be broken when full, or drop everything within for you to be forced to pickup everything.
6) I kind of enjoy it like this when thinking Minecraft-like. I guess Red51 could add back-packs, carts, and etc for water pipes, and all those heavier bits & pieces. Having to move bigger stuff with other equipment. As for running back and forth: That should be standard, yet also giving weight & function to horses & other modes of transportation.
7) More variety in weapons, armour, and tools should be a must in this sort of game. Even having a customizable statue.
Would be sweet to be able to jump realms while carrying items from one to the next. If it's done like Twilight Forest mod for Minecraft then I can approve of it. It however needs to be done cautiously.

9) More banners, coats of arms, and etc would be awesome. I guess you should use Posters for now, yet be awesome to be able to put default and other sorts up there. Larger statues would be sweet.
10) I would support movable blocks & such, similar to Minecraft's pistons & such.
11) I'm sure we'll have conveyor belts & mining railways & etc. I'm having high hopes for this.
13) I support this thought, more so after the Moose trophy addition.
14) Having fly-mode could be an admin-only bit. Neat. Well I do support this but has to be a bit trickier to get to so people don't abuse it. I'd recommend adding in various building supports & etc.
