Hi @Edoedoedo,   The current plan is for SAS Studio 5.2 to be available near the end of this year, but the date is not set in stone.   I am not able to reproduce the unresponsiveness working with a large program in SAS Studio 5.1.  I opened three large SAS programs (32107,  7123, and 6566 lines) and had no delay when editing each.   Sorry you are experiencing poor performance.  It would be good to report this to SAS Tech Support to see if they can help diagnose, and so they have a record in case others are experiencing.  In the meantime, SAS Studio 4.4 is available with SAS Studio 5.1 deployments.   Thank you for the feedback.   Casey ...
