Why don't you leave a message for the developer(s) on the addon screen for the tool? It's the best way to get the attention of the person or group that has developed the addon.
I did but as i said they probably arent working on the project anymore so do you know any good pushback addons?

You appear pretty convinced that it's a problem with the addon and not with your setup. Why? There are a lot of completely satisfied users out there using this tool with apparently no issues.
Oh, and the author will only update a stable addon if there is a reason to update it. The concensus appears that most people like it.
BTW, you claimed that you commented on the issue.
It's a pity that the most recent comment on that addon was 14 days ago, and wasn't from you. So, what gives?
