tile groups, save to file and load
From Nepster in IRC: Let people save/load tile groupings as a new terrain pieces. Groups can be saved as text files.
Groups may contain both steel and earth. They're special. I can't image-dump them with the Lix 0.3.5 tile formats, that would make an all-steel or all-earth tile.
Should probably implement a copy buffer instead of this.
I'd like a browser that offers all groups that the game has seen during this session. Instead of saving a group from level A to a file for the group's re-addition to level B, you load A once (even highlighting in singleplayer browser is OK) and then open B with the editor, open the group browser, and add the group.
Copy buffer is probably better than the { browser that lists all { tile groups that you have seen during this session } }.
Reason: That list will be bloated with rubbish groups that you don't want to see. Copy buffer works also for mere selections of multiple tiles, not only for tile groups.
