This plugin, suggested by @Guest0 and @Screwtapello , renders a summary of the current window’s multiple selections (ranges + contents) in a *selections* buffer.
It can act as a toolsclient, and live-update *selections* based on the… selections. You can edit ranges (but not contents), then use sel-editor-buf2kak to change the actual selections. E.g. you can delete ranges, modify them, or even enter ranges manually.
I’d like to implement selection-contents editing in the summary buffer, but I need to learn more…

Notes
I’ve managed to do this in pure kakscript, apparently transcending some language limitations
- looping: using
999q(macro with count) with a macro calling: exec iter. Alternatively, recursion-based looping also works, but hits a 100-level nesting limit (apparently, no tail-call optimization). - apply lambda to arguments:
def -override lambda-tmp %reg{a}; lambda-tmp args - stopping loops: with exceptions
- processing lists / shifting arguments: use
str-listoptions, andset global work %arg{@}; set -add global work %arg{1} - checking if arguments exhausted / list empty:
def nop-0_0 -params 0..0 %{}(call it on anystr-listoption, or on%arg{@}; it throws unless there are zero elements in the list). Any such param-count check is possible, either with predefined or on-the-fly checkers.
I’ve been able to implement a foreach, zip two lists, concatenate / prefix / suffix a list of strings, and it seems like a lot more is possible…
