Seeing another thread about "is XYZ plugin there or not" or "what may cause prim fail" i REALLY suggest that we should stop and think.. This plugin's usage logic is inherently flawed.. (or i would say outdated) What i would like to see one day is when i installing new code into image, it pops up a message: "Your VM missing an XYZ plugin for running this cool code, would you like to download and install it? Yes No " In case of Pharo, we should really start thinking about delivering quality grade solutions, not something which might work if you properly jump 2 times and whistle 7 times while faced North"... Look at what the practices which become common today in modern browsers, and OSes - they updating themselves without a notice and just asking you to restart it time to time. Why we cannot do the same? -- Best regards, Igor Stasenko.
