I suggest to add a $500 fee to any feature request. Everybody has great ideas. I could spend the whole day writing feature requests. But people will have to put work into checking and estimating the effort. If you want people to evaluate your ideas, you should at least cover the expenses.
I think I miss some important points to tell, first to submit an idea or ER you should be a subscribed and getting support from Frappe or any other partner, during implementation or support period as implementer or end user you discover some idea or small enhancement to complete the task easily with less headache where result and benefits is high. It’s not about writing imaginary stories. As a consultant I am getting requirements from client which is valid but not available and worth to be implemented. At the end someone will validate or reject those ideas or ERs.
