This mod has almost everything however i've noticed a distinct lack of dungeons and structures.
Any scan through sam's old update videos will reveal a bunch of structures and buildings that don't happen to be in the mod ranging from a dalek mothership to a town in trenzalore , it's quite clear from the dalek mod servers that you have the builders to do it and it's quite puzzling as to why these don't exist yet
some cool dungeons would be ~
Cyber Conversion factories
Flying Dalek ships ( maybe they can abduct you )
Zygon Mazes ( made out of human capsule thingys... )
SPACE DIMENSION
A Space dimension would be pretty cool and somewhat easy to make, simular to the minecraft void with stars and planets in the skybox where you could use to dump some locations such as space stations and cyberships that when raided can end up giving you tons of gold , perhaps you could even take over a cyber station and convert it into your very own space ship!
Secondary Inventory
This would allow for you to stack dalek mod items over your normal armours , two mods do this an example being galaticraft and another being dragon block C this helps for when players want to do something such as wear a mini me or the doctor's scarf but can't because they don't protect you from anything and end up being a waste of your crafting materials.
K9 STORAGE
Pretty simple suggestion , Right clicking on K9 will open up his compartment simular to a tardis door, which is then met with an chest GUI which allows you to put your stuff into K9, perhaps this disables flight or makes him slower to balance the effect of having this and as this is already in the game with horses and lamas i don't think it would be too hard.
TARDIS REBUILDING
too many times on the DMU i have been robbed out of my desired interior by crafting a tardis that still gives the default interior which ( and don't butcher me for this ) looks basic and ugly , this feature would add a compartment into the tardis that opens up asking for a new blueprint / circuit thingy used in crafting , by putting one of these in and hitting confirm you are teleported to a temporary glass box whilst your tardis is cleared from existance and it's spot is replaced with the new interior.
This feature would also help stop the too many interiors problem on the DMU as players would no longer have to make a new tardis for an interior change or new interior.
Okay so since your active and just generically like most if not all suggestions i was gonna comment on that but then i thought to not do it so i edited it to remove the comment , however now i just have a blank comment so im filling it in with this so it dosen't look akward.
P.S ~ you should add a system where users can delete fourm posts for reasons such as these. ( dirrected at the site admins of course. )
