            <label xml:space="preserve">- Helps to find duplicate lines and to visualize intersections
 - Works for self-intersecting lines too
 - Uses Bentley-Ottmann algorithm to detect intersections
 - Allows to separate different contour types by colors
 - Works with paths which have Live Path Effects (LPE)
 - Does not find overlapping colinear lines (sweep line algorithm does not intersect them)

Tips:
 - Convert your strokes and objects to paths before
 - Does not work for clones. You will need to unlink them before
 - Use extensions to filter short/unrequired lines
 - Use extensions to purge or repair invalid paths
 - Use 'Path > Simplify' or hit 'CTRL + L' to simplify the trimmed result. With a fine quantization setting the simplified paths will be nearly identical to the original path (except the position of control points)</label>
            <label appearance="header">Do not select too much paths at once if you have got a fine settings for quantization. This extension is slow and might calculate hours on ultra high configurations.</label>
