Alright, I haven't made a full diagram of guide transformations using handles, but looking at the different tiling types, I am now convinced at least that it is at least possible. So, with that in mind, I bring you YATTIP (Yet Another Tiling Tool Interface Proposal):

By popular (?) demand, this is now a tool again! (with a possible extra dialogue for extra options). The "handles" approach actually resolves a number of things. In fact, when choosing a guide, you now simple start with the following defaults: - P1 for wallpaper - Simple-rotation and scaling for radial tiling - Simple translation for line tiling (but all Frieze types are available)
Double-clicking a "tile" changes the toolbar into the tile edit mode. Using either the handle or a drop-down in the toolbar, you can then change the tiling type. Since for wallpapers, most people will be using P1 anyway, this approach should be satisfactory.
Other features I had proposed are still there: - Guide points and other guide types - Excluding parts of a tile's exterior and fusing all the tiles - Tile stacking should be still possible from a dialogue
Any major comments before I completely redo the wiki content again?
