==============================================
1- QSearch plugin doesn't have any previous or next button for cycling through search results. We can use Enter button on keyboard to cycle, but most of the time we use mouse.
I think there are two plugins named "QSearch::SelFindNext" and "QSearch::SelFindPrev" made for this purpose But when I try to enable them in plugins section, It shows me the following error and doesn't get enabled:
("QSearch::SelFindNext" doesn't support autoload.)

2-First, look at the screenshot below:

When I use Toolbar plugin with Multi-Window option (MDI or PMDI) enabled, they mess together and make it worse like the screenshot.

3- How can I add or remove my favorite buttons from main toolbar. Because there too many buttons that I don't want and need to be removed.
