GBIt needs some improvement to be a better product It needs some improvement to save .lp model. Some of the large models are not saved. It will be nice if it can track infeasible constraints the same as Gurobi. I also like to be able to import and export constraints from one model to another one. Such as selecting some constraints and import them in another model (in another Excel sheet).

GBExcel can become unstable Excel can become unstable. Many times i have to remove the Frontline add-in from excel to improve stability. I use the add-in about 2 or 3 days a month so this is not something that is all the big a deal. If i leave it installed i have more issues with excel freezing up or stalling and generally i dump the add-in. The installation and annual update process was greatly improved.
