I like how easy it was for me as an engineer who has never done programming before in Python or any other language really but just because of my experience with math formulas this program helped alot! It's not too complicated at all once you get into using some functions after awhile even though i have only been able use about 5 out 10 features so far its still very helpful!! The interface could be improved if they would allow multiple input files instead having one file per problem solved (which isn't always possible).
For example sometimes we need data from several years ago stored somewhere else where there are no backups available otherwise our job becomes impossible since solving each individual equation may take days/weeks depending upon size etc.. Also when saving models back up can become difficult due to large amount saved over time especially considering storage space issues nowadays unless your storing them locally then transferring takes lots longer compared to direct access through cloud services such AWS S3.
