Added 2 sizes of half cylinder fuselage doors to go on MK1 and Rockomax size tanks. They can be finessed to almost flush. Added a Sub Hatch for that underwater feel. Added a Star Trek/Wars style door that goes well on the side of Mk3 size or buildings. Added a 7 rung solid ladder with enough ladder collider overlap that you can have 1 per Mk1 fuel tank and be able to climb all the way. The gap between looks larger than the rungs but the Kerbal will keep climbing. Added a curved 7 rung ladder that goes roughly 2 5ths around a Mk1 and 3 of them together can get the Kerbal to go all the way aroung if you move in short bursts.
Made changes to the Ships hatch after being informed that an error was being thrown up by 1.12.2 Removed the offending redundant module and went on to correct and rebuild the model. It is named the same but anything that already had it on a previously built craft will probably have it change orientation and the node attach has been corrected. Also now uses the Internal used by the other flat doors.
