Thanks for the feedback! We’re always looking to improve usability in real-world scenarios, so hearing what you are missing is important.
The mouse scroll wheel might do what you are looking for in terms of zooming in and out. Using the scroll wheel you will zoom in and out at the current mouse cursor X position. Using ALT together with the scroll wheel you will zoom in and out in the Y axis around the current mouse position. I like to use the scroll wheel together with the Drag mode (keyboard D shortcut) to quickly zoom in and out plus left-click drag to offset the view. Does that at least partially help you accomplish the fine tuning of the view?
We’re looking into how to make selectable sample rate behave in the best way. Currently that’s all done as a post-processing step as part of the downsample functionality, this is something that that is definitely on the list of features we want to implement.
The scope mode sounds like a very interesting idea, it’s important to make people aware of the fact that the data isn’t being recorded in that mode though. I’m thinking that it may be a better idea to have a mode where you only keep the last x minutes of recording which will basically solve the issue of running out of storage space but still have the possibility to capture the moment something unexpected shows up? Either way we need to put it on our list of features to discuss.
