Hi wizball6502 !
1.- Yes, after buy you are able to dowload any future release or new content, maybe more tools or whatever i decide include in this pack.
2.- The problem is that the APP native resolution is 1280x800 , your height is lower than the native resolution so the APP makes a 0.5x scale to show all the content. I have in mind make the final resolution 1280x720 to fit with the standars resolutions, just started to add more and more features an withous space space i added more height without having in mind can cause problems like you so hope in next versions organize all better to solve this, sorry for the incovenience!
