Ok. I've started to play around with presets... And the first impression is: "damn I had to figure out which tile corresponds to which wall and width by myself". I wanted to create an easy and fast preset for random encounters... So I have created several "blank tile" variants (0,0 0,20 0,40 etc...) to have my non filled desert area look a bit random from time to time and here goes my first problem you can't change Variant for blank tile (You can ask why haven't I used filled tile well that's the next thing) I used filled tile (20,0 20,20 20,40) to have little houses, tents and some intractable stuff so I could use them to add "things" to the encounter just selecting a needed number (or even add some randomization in the process) and here goes the second problem... By default program creates a wall on the edge of the last filled tile. I don't need any walls at the moment in this preset at all and I left corresponding preset tiles places blank which result in not compilable map... Ofc I could have added "blank wall tiles" in the preset for the walls and use them to avoid this little thing but it leaves me w\o the ability to customize some walls with more complex buildings in the future and still use randomization as I had to exclude "blank wall title" which forces me to assign variant to tile and that rule will go for any outdoor maps you want to create...
In conclusion:
1) You need a decent preset creation guide (which tile corresponds for which wall in the readme at least)
2) Program requires a check box for edge walls if you plan to do outdoor maps with it
3) Program requires variant option for blank tiles
