Attached is a cut-down version of RPC's ODM Speedometer mod from xelerus.
It's a great little mod. It shows the playership's speed in small numbers directly under the ship.
The original full version of the mod caused a lot of lag the last time I tried it as it shows speed for all ships within 30 ls.
I felt this was too good to go to waste so have posted this smaller version.
It was very helpful when testing the Superfuel mod (search forum) which uses the object property 'operatingSpeed 'emergency.
Could also help testing drives, etc.
