Selecting row/column cuts in layouts

I'm writing a plugin with which has a somewhat similar purpose as the origami plugin. So you have the 'rows' and 'cols' keys in the layout which are arrays with floating point numbers in [0, 1] each of which defining a horizontal or vertical(respectively) line at the given percentage in the window. So the functionality in my plugin is splitting cells, merging cells, re-sizing cells and some other functions but these 3 are the important ones. What I could use if I could select the cuts or create new cuts with the mouse(inside a cell) or just select cuts and move them and by this define the cell merge, creation/split  and re-size. Also if touchscreen will be widespread this will be a pretty neat way to handle cells in sublime.
