Plug in-No escape hatch?
The Plug-in Icondrop is very frustrating and a hassle to use. The first issue is when you try to use the plug-in, You MUST sign up for an account. Well, that's when the second issue arrises. You MUST sign up for an account, there's no way to back out of it. You can't close the app, you can't save your work, you can't do anything unless you sign up for this stupid account. This is such a waste of time, and should be fixed or eliminated.
I think this is something the plugins can do better in reflecting. You should be able to hit ESC and exit the plugin.
Some plugins do require user accounts which at the discretion of the developer. We gave it a go on our end and it’s working so not sure what could be going on for you. I encourage you to contact Icondrop directly with details, https://support.iconscout.com/hc/en-us
