lowered the readsize (EXPERIMENTAL) from 10K to 2000 (originally) 1000. 10K caused high probability of xruns, while 1000 could result in stack overflow in gui-heavy patches.

added intelligent scrolling when trying to make connections between objects that do not fit on the current size of the canvas.

fixed stray bug where undoing deletion of objects that had preset_nodes associated with presets, did not reassociate them properly with the previously stored presets.

provided a more robust way of suspending dsp before closing the patch... needs testing to see if this fixes lingering sporadic crashes when quitting without closing the patch.

fixed bug where only one abstraction was reloaded upon saving one of its instances, vastly optimized the said operation from redrawing/cpu overhead perspective

added additional check to make sure clock_unset is not trying to unset something that just happened (may require further testing, based on one gdb segfault log)

reverted 0.43 backport as its implementation seems unstable when trying to (re)connect to jack via audio properties. Fixed a bug where closing jack while having DAC on would hang pd.

backported audio driver support from 0.43 and the pd/extra folder with supporting fixes/merges where needed. Removed outdated expr-help file in favor of new documentation.

fixed tooltip positioning on larger windows, fixed color inconsistency on nlets when used with tooltips

completed transition to the more optimized way of redrawing items on canvas following editing operations (e.g. cut/paste/undo/redo etc.). Implemented better version of the duplicate undo/redo action that also stores offset info

improved redrawing logic for undo cut/paste (need to check remaining undo/redo actions), other minor cosmetic fixes

fixed color inconsistencies in gop and array objects when selecting/deselecting, introduced optimized redrawing of gop objects

improved tooltip reliability in K12 mode, made preset_hub hidden in K12 mode in respect to tooltips, hopefully fixed dancing scrollbars with an ugly workaround

fixed nlets not being properly selected after gop object has been redrawn, improved redrawing speed with gop objects

improved redrawing of tooltip arrow logic to minimize visual artifacts during updating of arrow while maintaining mouse position within the same object

implemented universal catch{} for all commands sent from c to tcl to minimize (eradicate?) stderr output.
