First day of developing, I've found a few suggestions.
1,) Tile spread
You should be able to have an icon, like the 'MS Paint' bucket. [The fill all icon]
Select a certain area, select the 'fill all' option while you're laying a tile, and it
should do the entire area selected.
2,)Undo
An undo button, made many mistakes, would be easier to undo the mistakes
instead of re-laying the correct tile.
3,)New tiles
A way to be able to add your own new custom made tiles, this option would be fun.
4,)Saving
When you click on the 'close' icon in the top right (the 'x') a save option should
apear.
5,)Load-up
The map should be on small size, opening the huge map can be quite laggy.
6,)Resolution
An option to change the size of the screen? Re-sizeable?
[instead of dragging it]
7,)New gui?
The current gui is odd, and quite hard to understand.
When you highlight over an icon, no information apears, this should be added.
Add a scroller to the map, Instead of using the arrow keys.
[both options should be there, but a scroller would also make it better.]
The interface:
Doesn't look too good, but this is a draft. New stuff include:
'new icon' - Creates a new map.
'tile select' - Simple tile select. [Could also have a list box, for the type of map.
Inside Map tiles, outside map tiles, dungeon tiles etc]
'message bar' - Where the Startx/y/z are, could also be a button, to save up space
for the map.
8,)Custom Map size
Enter your own values, for the map size.
9,)Straight Tile Lines
Holding down a key, will produce a straight line of the tiles.
Will find some more, feel free to bash these comments.
