Hey everyone, here is the 3rd beta of Blocs V5.1.4. To address a range of ongoing issues, I have rewritten and modernized the drag and drop functionality on the design canvas. I’m still working out the last few kinks but overall its a lot better.
More fixes coming next week
Happy testing and have a great weekend 
Ok I’ll have another look! 
First weekend 
I’ve found it, I’ll get this out next week.
Hi all + Norm,
I think I found a couple issues that seem to affect this build, as well as earlier versions.
First, I inadvertently added a PDF embedded asset to my project that had an apostrophe in its name. The PDF asset worked fine when used in a download file link, but the function to “Find All Unused Assets” seemed to now be disabled, even though I knew there were unused assets. Once I renamed the PDF asset to remove the apostrophe, then the “Find All Unused Assets” function worked correctly again.
Secondly, when setting a logo graphic in the project prefs to be a Favicon, this logo graphic will show up in the “Find All Unused Assets” list as an unused asset, which I’d think should really not be listed. This quirk caused me a couple problems in the past when trying to clean up my asset list and then updating my project.
Hope this helps anyone else with similar issues.
Found an issue with Class Manager, which is also present on v5.1.3
On certain circumstances, the class manager replaces underscores with hyphens in the class name.
Examples:
If you create a class called: photo__img
And later edit the name to something like: photo_img, it will change the underscore to a hyphen
Additionally, change any class name to contain underscores, the class manager will change those underscores to hyphens. For example, you have a class called ‘photoimg’ and you change it to ‘photo__img’, the class name will be changed to ‘photo–img’ instead.
Happy weekend all!
