I like that this software does exactly what it says! It merges many files together to make large maps easier/faster than manually doing them one by one (like in ArcGIS). This process can take some time depending upon your internet speed but once you get going its not too bad at all.
The only thing i dislike about this program so far are minor errors when merging multiple PDFs into 1 file which results in small lines where they should be merged as well instead of just leaving 2 separate pdf'sβ¦
