I hope you are doing well!
We want to first apologize for any inconvenience or problems that this issue caused you.
We did reproduce the issue related to the search bar and found that a source of this issue is related to MonoDevelop functionality.
The Welkin Suite for Mac is based on MonoDevelop, this would be difficult for us to find a way to avoid this issue. However, we keep tracking the updates for MonoDevelop Shell, and, also, we will do our best to find a way to solve this on our side.
At this moment, we continue looking for the fix for this issue, but it is not so simple problem to resolve. I have just extended your subscription for 2 months for free. We hope this experience doesn't tarnish your good opinion of us :)
If you have any other questions or suggestions, please contact me. I will be happy to assist.
