[TYPO3] TS condition : check whether plugin X is on page

[Xavier Perseguers]

Hi,

I would like to change page generation processing based on whether 
plugin X is present on page or not. Is this possible?

If not, is there a shorter way than below to check whether current page 
UID is present in a list of values?

[globalVar= TSFE:id=10,TSFE:ID=14,TSFE:ID=id=34]

having 10, 14 and 34 stored in a TS constant of course...
