I understand that Kobo focuses on to optimize
- shop integration
- improve personalized recommendations
- other measures to
boost Kobos booksales further and which most users will understand. Kobo has to become or stay profitable to stay in business.
The general message in this thread is mainly "don't mess with the reading space (too much) and use this space (more) efficient."
The advice given may be called naive as it might suggest that developers or other involved Kobo personnel were not aware of "the problems/issues" or as it had not been part of the decision-making process.
The suggestions made by users, feasible or not are primarily expressed to motivate their complaint and not necessarily a "(you must) do this". It may feel that way, though.
We could also start a poll with just one question: "Do you like the new top header that Kobo introduced?" Answers to choose from: Yes, No, Doesn't bother me.
Regardless the poll outcome, it doesn't answer the question: Why?
Or, What can be done about it to improve it - keeping all corporate (financial budget) restraints in mind.
