I see that due to the new toolbar customization features that the display option 'hide seperators' has been removed. I would like to see this option returned (or a suitable replacement). I understand that /toolbar -h sep1-9 can be used to hide them, however the state is not remembered when mirc is closed which means an on start must be used to hide them. This is 9 individual commands since none of the /toolbar flags support multiple id/names.
My suggestion would be for the option to be returned, which would internally perform the commands to hide the default seperators, or just skip loading them to begin with.
Additionally, a 'transparent seperators' option could be useful, so that the gaps can remain while the seperators can not be seen.
