there are a lot of long time paid members here who would truly help you thin out requests for things that are already available or are simply impossible. unfortunately there is no method for commenting. I do understand that you don't want a constant gaggle of nonsense to sift through. But perhaps pro-users who have paid for what is the best SMS app out there, could also be provided the means to comment on threads. Or take it a step further and realize that some of us out here What actually pay a couple bucks for the opportunity to provide free help for you.lol I'm not kidding. I've seen numerous posts were people have said they would pay more if they could. So call them out by providing an opportunity for them to do so and get free help in return. Lol
What recent example is a post I saw or somebody was requesting the ability to save parts of conversations to the new keep capability. It's already built in. You share the thread to text Textra though and not keep notes which is a Google product. Then select keep as the conversation to save it to. It would have been fantastic to be able to respond on that person's thread and let them know that they can already do what they were looking to do but there is no way to do that.
