A nice feature which would not cause any problem with the variety of version schemes is the following.
Add-on updater could have a button "Skip this version" in the Update window. Taking again the example of Tony's enhancements: * 1.13 is installed on the local computer * 1.10 (being the one on the community website) is offered for update When the update is offered, I select the line of Tony's enhancement add-on and press the "Skip this version" button. This remove the line of Tony's enhancements in the update window. And Tony's enhancement update will not be offered anymore until the version on the community website changes (to 1.12, 1.13 or 1.14).
Would you accept to implement such a feature? Many thanks.
