JuhaManninen: at this time no. Want know opinion another developers - how it'll be better - red rect of component not in filter list or clearing filter when select component not in filter list and then click to his property in Object inspector. Think 2nd - easier.
Btw: today I get last trunk of Lazarus, build it - and every time I do this I see more and more interesting and useful thing. Only speed of building make me some worry. Whatever I do. I lose full 1 day at this problem, install RAMDisk, copy FPC sources and my project at virtual drive, experimenting on tuning options, disable logging, disable even many hint and warning message and... maybe 4 seconds(from 40) I win. And in end of the end, uninstall RAMDisk, and take a rest))).
