I have decided to get entirely rid of the "jumping" feature. My reasons:
It was completely broken and unusable all the time and nobody complained.
It was bound to the use/open key which made many actions ambiguous, e.g. when hugging walls searching for secrets, which further added to its uselessness.
There are already plenty of jump pads and elevators on ROTT's maps, wherever it makes sense, so the additional ability to jump is really superfluous.
