Feature Request: Enable/Disable checkbox beside each folder pair

[njminchin]

Hi,

I use freefilesync to manually sync (mirror) one particular folder on one machine to a number of other machines on a network. The problem is that sometimes some of these network machines are offline and it takes a while for ffs to timeout for these machines. Sometimes I will also just want to sync files to only some of these machines when testing, so it would be very handy to be able to simply disable folder pairs instead of creating a new sync or deleting the folder pair.

Anyway, thanks guys and gals for the great software :)

Awesome work
