I was happy to see you released a new version of the plugin.
Unfortunately, you totally changed the philosophy of your work.
Before, it was taking only one minute to create multiple ads.
Now, with this version, everything takes more time.
So, I know, the thing offers others functions.
But the new version is just less interesting to insert ads in sidebar.
Last not but least, you didn't update the previous version for years.
I hope it won't be the same for this new version.
No update with a complicated core ... it means lot of potential bugs.
Organize everything around taxonomy means no compatibility with the previous ads ... and you don't provide any import tool. Sorry again but that's not serious. If we need to start from zero again, that's better to use another plugin which has not been discontinued in the post. You probably worked hard on this plugin and your work deserves lot of respect. But that's bad you didn't think about the consequences of all these changes.
