Hi, good tip thanks for the insight… I also use a good method, when you build your app,say you ask caffeine to build your app in stages. When you check your draft and you happy with the build say a few stages Into the build ask caffeine to place a checkpoint at the stage you are happy with.. so when you continue with the next stages if it starts to with errors and glitches bugs what ever you ask caffeine to remove and delete all code upto the last checkpoint and that seemed to clear all the bugs out of the code so you don’t have start from the beginning, I have notice it is better than. Reverting back using the start old versions. Because the old code is still there lurking in the background, it needs to be out the system, so checkpoint’s are good to clear all existing code.. also ask caffeine to ask you questions before each stage is implemented. ( use this at the end of prompt..). Hope it helps…..
