lib not available and removal when network is down

Hi all

so I have been using YACreader for years now but something has been always bugging me and only found out today there is a forum

so my main comic library resides on my NAS (Qnap). my YACreader Mac app points to a dir on the QNAP but when the network is down or QNAP is in maintenance I always get this warning when I open YACreader "

"Library 'ik_comics' is no longer available. Do you want to remove it?"

I find that I often almost accidentally press yes..which is very annoying

so my question is

1) can this be a user option? can I just disable it and never have the option to remove a library

2) how does one back up the settings and metadata of the library in case I delete it by accident

thx a lot

Z
