Thank you for this helpful info! I’m so excited about .plusMillis() !! 
I’m using VSCode right now as I write this and believe I’ve mostly figured out how to use many of the helpful features, but not entirely. I’m familiar with/am a fan of the error high-lighting/little squiggly orange underlines and red circles next to rules, and I have kind of figured out the auto-suggest feature, but I wish there was like an index or a more helpful wizard or something. I know I can begin to type and it will load possible command snippets/variables which I can select with enter… and I think I can “query” it with ctrl-space, but I don’t feel like I’m seeing a list of all possible strings/actions. Like, I wish I could see in detail every possible API function/call/action/transformation/manipulation, etc. directly in VSCode… with a brief explanation + example/link to more details for each item, in a hover-caption or index or something. I also see my openHAB server folder structure/files + Items/Things and their status in the side-panel, and I know I can right-click items and make rules/follow the link to their Paper UI home which is cool, but it’s all still not quite completely intuitive for me yet. Wish there were more wizards/auto-generator tools/drag-and-drop type interfaces/etc.
Also, I think supposedly I’m able to run openhab-cli commands directly from VSCode, and also am supposedly able to see the log somewhere in VSCode, but I haven’t for the life of me been able to figure this out. Can I edit HABPanel in VSCode, or preview it live? I know I can edit CSS for HABPanel vis VSCode, which has been helpful.
