From the advantages of cooperation it is worth noting the contact and timetables (the project was extended for a couple of days due to a delay from my side).
But there are also very small disadvantages, if you can consider them. The main thing is that it is not very flexible file structure (there was no flexibility requirements in the project). Therefore, if it is necessary to do what to do (which has occurred in the process of work), it was already quite difficult to do it. That is, everything is done under the conditions of the project, neither more nor less.
I am pleased with cooperation and the result. If necessary I will contact you.
