Mark already (successfully) uploaded logfiles
Scrolling <-> check / uncheck of log files
If one log file fails during upload, do not fail automatically on other log files.
"I have many logs to upload on DLB. When I scroll down with the finger, the logs that I checked on the top are unchecked automatically.
If some logs are uploaded on DLB and if I upload new logs as well as one already uploaded, the upload fails for all logs. So I need to go through the logs one by one and delete them after upload manually. It would be good to have a number on the left to see the number of logs that are available."
