With the watchlist editor you can add new addresses or remove existing addresses from the watchlist that you're editing.
To add an address, click the 'Add address' button and press Ctrl-V on your keyboard in order to paste an address that you've previously copied to your clipboard outside of the ReQorder app using the Ctrl-C command. To remove an address, select the address that you want to remove and click 'Remove address'.
At the bottom of the panel is a list of all the addresses in this watchlist, when you select an address you can choose which data you want to ReQord for that address. When you select a new address the changes you made to the previous address will automatically be saved.
Note that if you enable the 'balance' checkbox, you can set the balance update treshold, which means that an entry will only be ReQorded in case the balance for the selected address has changed with at least this value.
Also note that any changes made to a watchlist will not affect any database until you have aplied the watchlist to that database. When you change a watchlist and want to apply it to a database, you need to click the 'Apply to database' button in the watchlists manager.
