The zip file above is still the latest from me as I have not looked at it for some time. Obviously you have to implement the patches build both the firmware and the application (I only ever built the app for Android) which make it difficult.
If I get a chance I will revisit the changes but I am find the spare time hard to come by these days.
While they would be nice to have I don’t like your chances as some of the requests are specific to WA so implementing on a device that is global doesn’t make sense. If I do get a chance to look at it again I may add day and/or time but even that given my limitations probably won’t happen. Ray also would need to accept any changes specially from the web server side unless people are self hosting or using a patched app.
