While I support the idea of removing things to streamline the program, mightn't this have the potential to impact significantly on the effectiveness of the community of helpers in the Windows/Mac forums, etc?
For example, if someone has a problem with BIAB 2016 (say) and I ask them to describe the process they go through that causes the problem, I can presently re-create their actions step by step (mostly). If things change too much, though, that would not be possible. Similarly, if I give a set of diagrams and step-by-step instructions on how to solve a problem, those solutions would be based on my current version of BIAB and if the change between my version and a user's version is too great, my solutions would have limited value.
Explanation-type problems that arise due to a lack of consistency between versions can already be seen in some posts in the "Tips and Tricks" forum where present versions of BIAB don't have an exact relationship with past versions.
For example, the below set of instructions regarding plugins is relevant to BIAB 2018.
https://www.pgmusic.com/forums/ubbthreads.php?ubb=showflat&Number=451623#Post451623 The system is now completely different. If a user of BIAB 2018 had a plugin problem, solving it becomes much harder if the solutions are based on BIAB 2024 as the reference version.
