“‘Position’ cannot set parent-child hierarchy, so if too many ‘positions’ are added, they fill the screen and cannot be collapsed. Also, configuration information such as position notes cannot be exported as a configuration file. When I put the portable version on a mobile hard drive and open it on another computer, it shows the information from that computer instead of the information I stored on the mobile hard drive.”
Regarding the portable version there is a special way to start the app in portable mode which is described here: Installing TagSpaces | TagSpaces Docs
I can not fully understand your first question, can you give an example ?
