Gosh, you have a strange misconception that Lazarus developers prevent the IDE from getting better. No, in reality they are the people who brought it even this far.
Juha, you have a misconception that I have a misconception 
I just wanted to say that original Delphi IDE design is not the way how an IDE have to looks like in 2015. I've never said nothing against programmers who did an excellent job. Just wanted to say that someone must to work on a more comfortable environment design.
Strange. From your first post to this thread
If I may to ask, why Lazarus programmers stubbornly insist on this archaically designed interface instead of creating something more useful and more productive?
-------------------
So, instead of opening useless votings and complaining, please improve the IDE and provide patches. Valid patches are usually accepted.
It is not useless at all. Voting shows that many people want to see changes in IDE design.
This was well known, and agreed long before this poll.
And yes "Someone" has do to the work. Who will it be?
The "Lazarus Team" is about little over a dozen people. All of them doing this in their free time, next to a normal Job, just in the evenings. Some can afford time every week, others only once in a while.
And together they currently already have over 1600 issues to deal with from mantis. Many feature requests, and ideas of their own (well doing the work, it is only fair to be allowed ideas of your own, isn't it?)
Still one of them started Anchor docking, and time permitting will finish it (or some one else from that team will).
Until then the choices are:
- wait
- do it yourself
- lobby for some one else to do it
