settled on zoom (ctrl+mousewheel) which does the same thing as font resize simply because doing real zoom is extremely cumbersome with tcl/tk (esp. when one considers resizing images and also re-adjusting all coordinates inside c code to match newly zoomed state)

Added undo font size, overhauled font resizing logic (x/y scaling is now bound to font resizing), added zoom option (ctrl+mousewheel), minor code clean-up, dynamic font resize improvements to the tooltip system and improved tooltip arrow appearance.

improved vslider: added pass-through for externally entered values (vslider_float) without having them corrupted (only if it is linear entry, log entries have to get recalculated for obvious reasons). also added automatic repositioning of knob when resizing both via clickhook and properties window.

added ability for hslider to pass through uncorrupted values (if entered externally via inlet) and to resize its knob properly when resizing via clickhook

removed selection from the undo queue as it precludes selecting older stuff and pasting it into new stuff (undo -> select old would purge the queue ahead of that undo, so -> redo -> paste would be impossible)

fixed automatic resizing of the gop when changing font sizes, complete overhaul of the tooltip engine. TODO: add proper nlet tags to iemgui objects...

added support for tooltips (based on the http://sourceforge.net/tracker/?func=detail&aid=2838176&group_id=55736&atid=478072)

by tag in which case gop will fall back to the old way of redrawing

fixed all iemgui objects to conform to the new model of gop selection (no highlighting of objects inside gop unless they are toplevel objects)

altered behavior of gop objects so that internal elements are not visibly selected. Also reworked the way array and scalar selection is dealt with fixing segfault and making a more fool-proof way of selecting them.

improved logic for moving gop objects by checking if the gop has any legacy objects inside it that don't support displacefnwtag

improved out of focus typing behavior by including focused window information to the canvas_key function

further refined calculating size of g_mycanvas (when inside GOP getrect returns full size, whereas when on the toplevel canvas, it returns only the selectable rectangle)

fixed recreation of abstraction after saving it in its own independent root instance due to stale canvas_undo call that is not being used any more.

made gop resize and move hooks visible only when nothing else is selected on that canvas to minimize possible overlap of selection hooks

fixed bug where gop element with hidden text still did not allow resizing below the width of the text

added ability to deselect currently selected objects from the canvas if focusing outside the said canvas window

added automatic focus of the root window at start-up and fixed copying text from the console window into the clipboard using ctrl+c shortcut

implemented free() calls as part of the pd_quit() call from the following sourceforge bugtracker: http://sourceforge.net/tracker/index.php?func=detail&aid=1502860&group_id=55736&atid=478072

fixed confirming saving changes on an abstraction hidden inside another patch (currently invisible) whose prompting failed...

made openpanel and savepanel open by default in the folder where the original patch was opened from.

Improved logic for intelligent asking when to save abstractions. No longer is it necessary to check whether to save an abstraction after it has been changes and only displaced on parent. this is because objects are "activated" when selected which potentially means that abstractions would be recreated as soon as they are deselected essentially making user lose anything they changed in the abstraction and did not save. However, in pd-l2ork we check when objects are activated whether their rtext (and therefore also its arguments) have changed and only recreate object if they did.
