[Lazarus] question and suggestion

[FreeMan]

Hello,
Question is, why lazarus profile folder is hidden? hide from whom? I'm 
talk about linux, I don't know other platform, not sure but osx same 
too, hidden folder.  profile folder name start with "." I mean.

suggestion is lazarus app (exe) can in profile folder. why?
if wanna use multi source (version) of lazarus you have, can make multi 
profile via  ./lazbuild --pcp=~/.lazarus
I have one source (version) of lazarus, I need multi profile , for test 
and normal etc.

if lazarus application make in profile folder, can "lazarus source root 
path" add in application or better way can write in one setting file. 
similar fpc and fpc source folder.

if some one say yes useful this idea then open suggestion on bug tracker

thank you
