Hi Sid,
thanks a lot for your feedback!
All of the requests you mentioned are planned, please keep in mind that the whole App is build from scratch in the last 8 weeks or so. There is much to come. It will, however, never be a GCS clone. The app will focus on usage "in the field".
For the logs, you just need any other app that receives files, for example Google Drive or Dropbox or Google Mail or WhatsApp or Telegram or whatever. For example, share the log with your Google Drive, sync it to your computer and use GCS on your computer to replay.
Thanks again for testing!
Marc
