see attached document. try adding text to all three connectors. text is placed 
in especially strange location for upper right connector, but others are not 
much better.

so, placement for text on connectors should be better (and probably also 
customizeable).

1. if possible, it should stick to longest horizontal section of the connector;
2. if there are no long enough horizontal section, it should stick to longest 
available vertical section;
3. on both cases it should try to be either up/down (or left/right) of the 
connector so that smallest possible amount of other objects is covered;
(what should be done if there is not enough room either on horizontal or 
vertical sections ? maybe choose longest available and overflow ?)
4. there should be an ability to drag this text to any other section and side of 
the connector line (even to those where it sort of doesn't fit - in this case it 
overflows that section);
5. some limit for overflows probably ? what does it do then ? font reduction 
might be one option, but line breaking probably is better.
6. there should be an ability to define distance for text to line, overflow at 
which other methods are applied, choice between line breaking and font 
reduction, preference for left/right and up/down placement of the text.

ps curent option "adjust to contour" doesn't work; also controls in 
"dimensioning" tab don't seem to work to achieve this.
