One way to make the selection task easier is to use selection filters to prevent the selection of certain types of objects. This way, only the relevant objects that you want and needwill be able to be selected and all others will simply be ignored.
The problem with this is that the Selection Filter options are inside the Select menu and the Selection Filter submenu is not capable of being disconnected and changed into a floating panel. So, you would need to disconnect the whole Select menu (and this menu is quite large).
That is why I created the Selection Filter ON/OFF plugin.
