Hello, I recently un updating to version 2016.I put the list of problems I've noticed about the previous version using des estava 2014:

1. The management of layers in paper space is not better than the previous.
2. The order regen not work for me.
3. Changing window in paper space is very slow. Before pasava not.
4. Editing blocks slows down work and when not maintained properly keep the order of the layers, as regen work program have to close and reopen.
5. The slow pan and zoom works very well.6. Continue some problems in editing text.

In general, work with the new version is much slower than the previous one, not I can do to optimize or improve performance.
