portability and "sensitive" files

[Admin]

meanwhile, I changed a powerline on my desktop computer and this resulted in a total mess:
1) all my chrome and cent browsers disconnected from sync on all 3 machines (desktop, laptop, work desktop), i.e. 3*2=6 browsers,
2) after signing in to sync again, my bookmarks became a mess too: many duplicates: 50 duplicates in one case,
the order was changed in some and even a whole folder was duplicated!
come on google, really???
just because I changed a powerline?
why does your browser have to be so dependent on the machines?
this is terrible implementation

Chrome sync is not robust enough today.
