Thank you for your contacting us with these questions.
May I please ask you to open the Organization that you used as the target one for deploying and check the Deployment status (Setup / Deploy section / Deployment status). Please tell me if there is any information related to your deployment process from TWS in the list of the failed or succeeded operations. If this is present, please let me know what are the details for this operation.
This information will help us greatly to understand the reason for failed deploying and to know which error TWS doesn't show.
Currently, there is no ability to exclude tests run after deploying files to another Organization during the deployment process in The Welkin Suite IDE. This option is included to our working plan for the future versions of TWS. Right now, I'm afraid, I cannot tell you when exactly this will be implemented.
In addition, we are going to change the deployment process using the Ant. This will help to improve the performance and usability for this functionality.
As for the ability to save the settings for your target Organizations, we have this on our backlog also, but this will be implemented after the previously mentioned changes.
If you have any other questions, please contact us. We will be happy to answer them.
