### Last week:

    * [spec2] fixed the last remaining issue with full-replace layouts.
    * [spec2] fixed the visibility of windows on gtk: the backend was drawing windows before receive
    the open message (because of the visibility settings)
    * [spec2] made a mock up of “generator based list presenter” : a way to not need to feed all items to 
    a list before displaying them (this should sped up big lists, and rescue the fast table main purpose). 
    * spent part of the day looking for improvements on the callback speed. Figured out looking for
    a callback by address is time consuming because it makes an #isKindOf: very frequently. I made a
    PR to make the comparisson faster.
    * [big-images] made calypso modification about TabManager go into Pharo8 (maybe issues remaining?
    We will see, hopefully not).
    * [big-images] start analysis on speeding up senders/implementors/references (this should also help for
    refactors later)

### This week: 

    * [big-images] finish senders/implements/references speed up
