[HOT] My tips and tricks for JOSM to mark faster the damaged and collapsed buildings - http://tasks.hotosm.org/job/350

For faster marking damaged and collapsed buildings (task http://tasks.hotosm.org/job/350 ) in JOSM, I developed few tricks, which makes the whole process faster. The only extra thing you need is to install utilsplugins2 . 

First, by pressing Ctrl+w you will make all the objects transparent. That is necessary for viewing the current status of building. 

For filters: if you don't want to be bothered by some elements (for instance landuse=residential in the big cities), you can just add new filter and write into input  landuse=residential to hide it. By checking the second checkbox (Hidding filter) you can even get rid off the borders of element. 

But the most powerful thing about filters: if you add new filter building=collapsed and building=damaged, you can easily see what is already done (even when the transparency by pressing Ctrl+w is active). 
If only few buildings in the area are damaged, but most of them is collapsed, you can easily mark the damaged, then by dragging the mouse over the area select the rest of the houses, in main menu go to Selection → Unselect nodes (make sure no other elements such as roads are selected) and you have selected the collapsed buildings only, which you can marked as building=collapsed in one step. 
At the very end, when you have to add typhoon:damage=yes to every single building, you can just click onto the third checkbox (on the very right of screen) called Inverse filter (which show nothing but what is in the filter) and on the map are only those elements mentioned in the filter active (for instance on filter building=collapsed only those houses). Drag over whole area you have been edition by mouse, go to main menu →  Selection → Unselect nodes and you have only building=collapsed selected. Add typhoon:damage=yes and do the same with building=damaged
