Hi! thanks for the feddback!
1) What do you mean with all the commands? I may add shortcuts without the need of a menu bar.. would it be enough for your needs? Perhaps i cann add them for 1.6 (1.5 is almost ready).
2) Does any message appears when pressing "Export All..." i'll try on a windows machine later, but i think it was working. It exports the maps in the same directory the original file is. The top export button bug is fixed for next release.. i found it some days ago. The preview is not exported in 1.4, because the purpose of Laigter is to export maps that are used within shaders. I added the feature to export preview for 1.5, but just of the texture currently selected due to some internal problems.
