Thanks Dmitry !
What I meant is that I feel that the bar or toolbars at the top takes a bit to much space.
There is :
------------
One linebar with : File ......Help > and the rest is free space........
------------
Next linebar is : the folders ...setting ,etc......If you could just move this bar to the above ,next to the help (combine this bar withe the bar above -all in one line) ,it would be much better ,it would have a better look and also give a bit more space to view the bookmarks or the browser below.
-----------
You can also try to see how it looks if you reduce the size ,a bit ,for some bars ,as all such small things put together can give
a better or larger view.
This are just some small things that can be done.
And it is just my view on this ,at this moment.
Otherwise you are doing a great job.Please continue.
