It was formerly a simple matter of cutting and pasting from a unit.gif from here or the Scenario league and into the orignal.gif file. But I have not had any luck whatsoever finding an Android ap from Google Play that can accomplish this. Nuts. Most of their aps are made for photo editing or vector graphics. Some can't even open a gif or bmp file! How crazy is that? While they do have a crippled version of Gimp, it is so buggy as to be nearly impossible to utilize. Ordinarily in a laptop version of Gimp I could do this in minutes. Does anyone have any ideas who uses a tablet regularly? I only want to replace four units. At most this should 15 minutes as it means cutting and pasting two units from two other scenario files into the main one. But I have no access to a desktop or laptop at the moment, only this tablet.
