Let me just start off by saying I love this mod and everything that it does by itself. Thank you so much for making it. I've tried all the parts failure mods around and I like the experience that BARIS the most by far. That being said I play with KCT which I also love, and I love that this mod integrates with it but I do have one tiny thing that irks me about it. I may be alone in this but I truly hope you consider this as an alternative integration option.
I feel like KCT integrates with BARIS in a way that makes the integration feature of BARIS unnecessarily dichotomic with the construction aspect of KCT thus removing a feature of this mod I rather enjoy and simply replacing it with what I feel is a slightly different feature in KCT. In my eyes, integration and construction do not necessarily have to be mutually exclusive. I rather enjoy the option of investing additional time into a rocket to make it more reliable and I simply do not have that option in KCT. I also do not have the option of paying workers which not only makes multiple event cards meaningless in my save but also removes another valuable functionality of the mod as an additional resource sink. In my mind the perfect integration between the mods would be rather than making the user choose between only one or the other method, to simply append integration after KCT does the construction phase. To be more specific my view of integration would have KCT complete construction, then allow the option of undergoing integration instead of rolling out to the launch pad while the craft is in KCT's 'storage'. Integration would function as it does in BARIS without KCT except that after integration is completed the rocket would be returned to KCT storage with the reliability points altered as needed. If it is rolled out before integration is done, then it would instead function as if integration was not done.
I understand this would probably require a complete rewrite of the KCT-BARIS interactions but I do feel it'd be a much welcome touch if only because I feel that KCT's time factor is more necessary as in building the rocket, while BARIS' time factor is separate and optional akin to stress-testing it and ensuring it functions as intended. Again thank you for making this amazing mod and for considering my humble suggestion for potential improvements.
EDIT: Also not sure if you're aware of this, but when KRASH is used with BARIS installed, KRASH simulations are always treated as if the vessel had not undergone integration which makes it difficult to use.
