I just added a new forum where we will document the changes we made to the ZeosLib sources in order to fit HeidiSQL's needs. Most of them are bugfixes, so they might be worth to find their way into the official Zeos-sources some time. For each change, a unified diff against the previous revision is included in the forum-post.
Ads were blocked - no problem. But keep in mind that developing HeidiSQL, user support and hosting takes time and money. You may want to send a donation instead.
