There are two Pen APIs in the Windows ecosystem: WinTab which is older, and Windows Ink which is newer.
OTD only supports Windows Ink so any apps you want to use it with must also support Windows Ink.
Most creative apps support Windows Ink - Clip Studio Paint, Krita, Photoshop.
If you want pressure sensitivity, tilt, etc. - you must you MUST configure OTD to use Windows Ink and configure your apps to also use Windows Ink.
By default, OTD has no restriction on the hover height of your pen. Most drivers impose an artificial limit of about 10mm for a pen. But you'll often find with OTD that the hover height is increased substantially.
The maximum hover height is dependent on the specific model of tablet involved. For example with a Wacom Intuos Pro (PTH-860) my hover height goes from 10mm with the Wacom Driver to 20mm with Open Tablet driver.
You can install a plug-in to control the hover height and have whatever limit you want.
OTD stores information in its application data directory

If you are doing more advanced things with OTD you should be familiar with this folder.
